How To Troubleshoot Your Car’s Stalling Engine

Eric Driver — Tue, 13 Jul 2010 14:21:05 +0000

Engine stalls can occur for many reasons, including failing sensors, compression issues, and problems within the ignition system. Unfortunately, today’s vehicles are designed with such a high level of complexity that troubleshooting the issue is difficult. There are many parts that can potentially contribute to the stall.

With this in mind, we’ll explore your car’s engine, ignition system, and other components. We’ll approach them with the goal of understanding which parts can play key roles in preventing your vehicle’s engine from running. The circumstances under which stalling occurs will, in part, dictate the components to check. This will become clearer below.

Check For Sufficient Fuel

Your engine obviously needs fuel in order to operate. But even if it receives fuel, the volume may be insufficient to keep it running. If your engine stalls while you’re driving, and the reason is due to insufficient fuel, the fuel pump is likely failing.

The pump is responsible for creating pressure in the line. If it fails, the pressure will dissipate, and your engine will receive too little fuel. This causes a stall. You will be unable to restart your car.

If your engine stalls when you try to cold start it, the problem is still likely to be too little fuel. But in this case, the fuel pump is unlikely to be the culprit. Instead, it may be a failing airflow sensor (described in more detail below) that is delivering bad data to your vehicle’s powertrain control module (PCM). This might be leaning out the air-fuel mixture in the cylinders.

Look For Ignition System Problems

There are several components that comprise your vehicle’s ignition system. These include the ignition coil, distributor, distributor cap, rotor, and spark plugs. These parts work together to perform a primary job: to ignite the air-fuel mixture in your engine’s cylinders. It accomplishes this task by transferring an electrical current from your ignition coil to your spark plugs. The transfer of the current depends on each part along the way.

If any component in your ignition system fails – or even falters – the current will be interrupted. This will cause your engine to stall. Related to this issue is the operation of your crankshaft position sensor (CPS). This is a sensor located in your engine that monitors your crankshaft. It sends the data to the PCM, which uses it to control ignition timing. If the CPS fails (due to wear and tear, or prolonged exposure to high temperatures), your PCM may lower your car’s idle, causing your engine to stall.

Are Your Car’s Sensors Failing?

Your vehicle is equipped with several sensors that deliver important data to your PCM. The PCM acts upon this data to ensure your engine runs efficiently. If any of the sensors malfunction, the computer will receive compromised data, or none at all. As you might suspect, this can lead to problems with your engine’s performance.

For example, the mass airflow sensor (MAS) is tasked with monitoring the amount of air that flows into your car’s engine. It relays this information to the PCM, which makes changes in the amount of fuel sent to the cylinders. If the sensor become contaminated, or it fails, the PCM may lean out the air-fuel mix.

The manifold absolute pressure (MAP) sensor also plays a key role. It monitors the load placed on your engine and sends the data to the PCM. The computer uses the information to optimize ignition timing. As with the MAS, a failing MAP can cause the PCM to lean out the air-fuel mix, and thus cause a stall.

Other factors that can cause stalling include worn spark plugs, vacuum leaks, a faulty exhaust valve, and even a failing coolant sensor. In most cases, troubleshooting the problem requires the expertise of a trained mechanic.

Choosing Good Car Repair Estimation

Ryan Array — Mon, 12 Apr 2010 18:34:19 +0000

Having a crash is probably the hardest situation that may happen to you and it is something that may show up anytime. Even though you drive very carefully under the velocity limits or even when your car is stopped someone who is not paying attention slams into your car. Your vehicle may also be damaged by earthquakes and you can’t predict these things.

If you need to get less worry you could always select a good auto insurance policy but normally insurance companies solve problems pretty slow, and you possibly want your vehicle fixed and running as soon as possible.

However if you want an instant solution you should know that vehicle repairs can get expensive and you always have to search the best repairs for your money.

It is recommended to estimate car maintenance costs before picking a company that would maintenance your vehicle. There could appear several cost differences for maintenance prices in different regions of a country and you should always pick the best choice for you.

If you have a scratched hood, small engine troubles, smashed bumper or a little damaged side skirts, these are problems that could be repaired easily and pretty cheap.

You have to know that minor repairs are pretty low-cost, but when it comes to severe vehicle damage then you surely have to be really careful when you estimate your vehicle maintenance costs. There are some companies that overcharge you for your car repair and you surely don’t want that to happen.

A vehicle maintenance estimate usually content of this information: your data and your vehicle data, replacement parts needed for the repair, labor cost, miscellaneous charges, flat fees and a summary of charges.

The labor charge is the number of hours spent to maintenance multiplied with the hourly charge of the vehicle service. It is wise to check the car repair estimate to ensure that you will not be overcharged.
