Refuel The Car And Fix Fuel Gauge

How to Fix a Car that Randomly Dies while Driving

Many times your car will start working when you refuel it. This is primarily when the vehicle runs out of fuel. Do keep in mind that you will have to check the fuel gauge. If it has any issues, then you need to fix them. A misbehaving fuel gauge will not give you the right indication of how much fuel is left.

Reasons To Stop Idling

A simple turn of your key can keep the air cleaner and save money and fuel. Every time you turn off your car engine in place of idling, you’ll:

  • Make the air healthier by cutting down on hazardous pollution in your town or community. Idling tailpipes spew out the same pollutants as moving cars. These pollutants have been linked to serious human illnesses including asthma, heart disease, chronic bronchitis, and cancer.
  • Help the environment. For every 10 minutes your engine is off, you’ll prevent one pound of carbon dioxide from being released . An EDF report shows that in New York City alone, idling cars and trucks produce 130,000 tons of carbon dioxide each year. To offset this amount of global warming pollution, we would need to plant an area the size of Manhattan with trees every single year.
  • Keep money in your wallet and save fuel. An idling car uses between 1/5 to 7/10 of a gallon of fuel an hour. An idling diesel truck burns approximately one gallon of fuel an hour. With average U.S. prices for diesel fuel topping $2 a gallon1, that’s about $2 an hour wasted.

The Cars Ignition System Is Not Working

Faulty Ignition Switch

If your car shuts off while driving, it might be due to a faulty ignition switch. Thats what happened to me. After I got home and checked my car for anything else wrong, I noticed the ignition switch was not working it couldnt turn on or off any of the electrical components in my car .

The faulty switch can cause a variety of electrical problems. Your car may have issues with the airbag system the power door locks, and you might even lose the use of your stereo or headlights. You may be stranded on a dark road waiting for a tow truck to arrive.

You should have the ignition switch replaced as soon as possible to eliminate this potential danger.

Faulty Alternator

If your car shuts off while driving, it might be due to a faulty alternator. The job of an alternator is to keep your cars battery charged. The more electrical components you have on your vehicle, the more load youll put on the alternator.

If too many electrical devices draw power from it, the battery will eventually drain and shut off your engine. The battery can die, too. If the battery is old enough, it might not be able to hold a charge.

However, some electrical devices can cause your car to shut off abruptly. If you drive an older model vehicle with an analog odometer, then the device called the odometer control module has probably failed.

Turning Off My Car At Stoplights

Dear Tom and Ray, We own a 2004 Honda Insight hybrid and, as you know, one way in which this car achieves its superior fuel economy is that the combustion engine turns off whenever the car comes to a stop. Our other car is a Subaru Outback, which gets half the fuel economy as the Insight, but we love it anyway. We happen to live in a city that has painfully long red lights lasting between 3 and 4 minutes, during which time we waste gas, money, and our lives. I have proposed to my wife that we could save at least the gas and money by turning off our Subaru while stopped, then quickly turning it on again just before the light turns green. Although good in theory, we were wondering a few things: 1) Would we actually save gas using this method? Ive heard that starting up the car uses more gas than when the car is just idling. 2) Will repeatedly stopping and starting the car damage it in any way? 3) Must cars be hybrids to utilize the autostopping technology? 4) Is there anything else we havent considered? Thanks for all of your advice over the years. Sincerely,

As a parts man , Ill be glad to sell you at least two more starters over the life of the car than you would otherwise have needed. cha-ching.

No dont do itit isnt worth burning up your starter with so many extra starting cyclesit would save some fuel howeverbut not enough to offset the starter replacements.

They do this on some Hybrids nowbut the restarting is done with that other electric motor.

My Engine Shuts Off When I Reach A Stop Light

An engine that stalls when you reach a stop light or while idling may point to a faulty idle air control solenoid . The computer uses the IAC solenoid to bypass the throttle valve and inject more air, depending on engine operating conditions.

A common problem with air passages in the throttle, and the IAC valve itself, is carbon, dirt or fuel varnish buildup. If air can’t go through the air ports when needed, the engine may stall when you reach a stop or while the engine is idling.

I had a problem with my car where it would randomly shut off while I was driving. The only way to get it back running is to pop the hood and disconnect the battery for 10 or 15 minutes. Then, reconnect everything and start over.

What causes this, and what can be done to fix it? The most likely cause would be the ignition control system in front of the drivers side strut tower. A known design flaw in most modern cars is that they will intermittently go on the lean fuel mixture.

When this happens, it will cause a temporary no-start condition until the problem can be isolated and repaired. This is due to a secondary air system in the intake manifold, which provides oxygen during cold engine start-up conditions.

Let us see other potential reasons for cars shutting off while driving:

  • Faulty Ignition Coil
  • All these potential reasons can be classified under 4 main categories. Let us see these reasons in detail.

    How To Diagnose And Fix A Car That Shuts Off While Driving

    If your car is shutting off while driving, here are some things you should do.

    • Start by checking the fuses. You can do this by pulling out each fuse and then replacing it to see if that was your problem. If not, move on to the wiring harnesses.
    • If you think there is a wiring problem, check all the wires leading up to your ignition coil. The coil needs the power to work, and if it is not getting that power, the car will shut off.
    • If you think there is a problem with your ignition coil, common causes would be loose connections or improperly installed spark plug wires.
    • If you find any corrosion on the connectors, clean them off, spray them with some contact cleaner, and see if the car starts again. If you still have the problem, there is likely something wrong with your ignition coil.

    The Steps To Follow When Your Car Shuts Off While Driving

    Needless to say, having your car turns off while driving might leave you stranded in the middle of nowhere, or become a safety hazard if youre driving at high speed or on the highway with a lot of traffic around. Follow the steps below to maintain the safety of yourself as well as other vehicles on the road:

    Pull Your Car Over To The Side Of The Road

    The very first thing you need to do when your car shuts off while driving is to try to not panic and guide your car to the side of the road or the shoulder. As youre slowing down to a stop, pull over to prevent any vehicles behind crashing into your rear, as cars on the highway often travel at high speed. Note that your car will be losing the ability to brake and steer, but this is your only course of action.

    In the case that slowing down your car is too difficult, try to find a safe place in sight off to the side of the road to guide your car to, and then engage the emergency brake. This will cause an abrupt stop, but its a hundred times better than abruptly stalling out in the middle of the road.

    Try To Restart Your Car

    Now that your car is safe off the side of the road, the next step is to check if you can restart your car so that you can at least drive to the nearest auto repair shop. If youre lucky and can determine or narrow down the culprit, you might in some cases be able to make your car restart.

    What Would Cause A Car To Shut Off While Driving

    How do stop lights “see” your car (to turn green)?

    Car shutting off while driving can be due to many reasons here are some common ones.

  • Operating Temperature Is Too High
  • Your car might shut off while driving it if your engine operates at a high temperature. If your engineâs temperature gets too high, there may be a problem with your vehicleâs cooling fan or coolant system. Make sure the AC is on and working properly to keep the carâs interior cool and prevent it from overheating.

    A fuel filter ensures no impurities or sediment get into the gas tank. If there is dirt or grime in your fuel tank, it can clog up the fuel filter. When this happens, the fuel pump will stop working and cause your car to shut off. If you suspect that your vehicleâs fuel gauge may be clogged, then get it replaced as soon as possible.

  • Faulty Crankshaft Position Sensor
  • A faulty crankshaft position sensor wonât allow the car to start because it sends an incorrect signal to the computer. It can be due to a bad CKP or a damaged wire. But either way, itâs usually not something that you can fix on your own.

    The same goes for a bad camshaft position sensor . Some older cars have both sensors in one unit, called a dual-map sensor. It has the same effect as having two faulty sensors thatâs why you cannot start the car because it can sense no crankshaft turning.

    In addition, if your vehicleâs fuel pump makes noises or emits strange smells, you need to repair or replace it.

    How Long Can You Ignore Engine Stalls

    It depends upon the severity of the symptoms. If symptoms are mild, you may be able to safely drive for days, weeks, or months with an engine misfire until it finally stalls out. But as a car owner, you will have to face your fears and take your vehicle to a qualified mechanic at some point in time.

    Car Systems That May Cause Stalling

    There are numerous systems responsible for keeping your car running. A malfunction in one of these may cause your car to turn off. The most common systems that will cause your car to turn off are the following:

  • The electrical ignition system .
  • The fuel injection system .
  • The cooling system
  • The electronic engine management system

    How Do I Disable This Feature On My Vehicle

    Some vehicles have a button to turn Stop/Start off for one ignition cycle. If the vehicle is equipped with the Stop/Start deactivation switch, you can push the switch to turn off Stop/Start. Stop/Start is turned off when the LED indicator on the switch is not illuminated. To help maximize the fuel economy benefit, Stop/Start is enabled each time the vehicle is started.

    When a car comes to a complete stop and idles for more than a few seconds, the engine automatically shuts off thanks to auto start/stop technology. The engine restarts when the driver applies pressure to the accelerator. Its easy, and some claim it can reduce gas use in stop-and-go traffic by 3 to 5%.

    Adjust The Distributor Timing Injector Or Ignition Control System

    Sometimes car dies while idling but restarts when your turn on the ignition, right? To address such a problem, you have to check three important components.

    The first part is the distributor if your vehicle has one. Using the right kind of tools, you need to adjust its timing.

    The second component is the fuel injection. Check this particular element with the help of a mechanics scope or screwdriver. Working injectors tend to make a snapping/clicking sound. On the other hand, no sound at all indicates a bad or damaged injector.

    The last unit to check is the cars ignition control system. This module is responsible for controlling the voltage timing. It ensures that the current traveling to the spark plugs supplies enough spark so as to ignite the air/fuel mixture properly.

    Take Vehicle For Comprehensive Ecu Inspection

    It is important to inspect the ECU from time to time. The ECU is an important component of the vehicle. However, when it causes the vehicle to shut off or misbehaves, then you will not be able to fix it on your own. You will have to get an OBD2 scanner to get some idea regarding the error codes. It is advisable to take the vehicle to a professional and have a full ECU inspection.

    Faulty Fuel Pump Or Fuel System

    A fuel pump supplies the engine with the correct amount of fuel. If the fuel pump does not provide the right fuel to the engine, the motor will shut off, and you will be left stranded.

    The bad news is there is no bypass for a faulty fuel pump you have to fix it or buy a new one. Another reason could be that your fuel filter got clogged, so the fuel pump cant pump fuel through it.

    A fuel filter is a small component whose only job is to clean the fuel that goes into the engine. If the fuel filter is clogged, the fuel entering the system will be insufficient, and the engine will shut down. Fortunately, it is easy for you to replace a fuel filter.

    Most fuel pumps are installed inside the fuel tank. A little mechanics secret is to give a kick with your foot or something similar on the fuel tank when the car shuts off. If the car starts then, there is most likely a problem with your fuel pump.

    Be careful not to hit it with anything with an edge, though, because the fuel tanks are made of plastic, and you may make a hole in it and that is the last thing you want to do!

    If your car turns off while driving but then turns back on suddenly, it can often be due to a bad fuel pump.

    Clogged Or Damaged Fuel Pump Or System

    Provides the Engine with Enough Fuel

    If your car turns off when you stop accelerating, a malfunctioning fuel pump may be the cause. For combustion to produce enough power, your engine needs a precise fuel supply at an exact moment as an input.

    The fuel pump is the component that provides the engine with enough fuel. It is similar to your car running out of gas when the motor shuts off if the engine doesnt receive the proper amount of fuel at the right time.

    There is no bypass for a malfunctioning gasoline pump, which is bad news. You will need to fix it or change it altogether.

    Blocked Gasoline Filter

    Your gasoline filter can also get blocked. The primary role of the fuel filter is to clean the fuel before it enters the engine.

    The fuel pump may eventually become blocked with contaminants from old gasoline, which will interfere with the engines capacity to produce power and cause your car to shut off when stopped or slowed down.

    Nylon or Paper Fuel Filter Needs Replacement

    Replace your fuel filter if it is made of nylon or paper. If it is metal, all you have to do is clean and repurpose it. The majority of fuel pumps are mounted within the fuel tank.

    If the car starts at that point, your fuel pump most likely has a problem. The tank is composed of plastic. Therefore, do not bump it firmly with a metal object as you dont want to break it.
