Car Hesitates to Start and Check Engine Light

What Does It Mean When My Car Hesitates to Start and the Check Engine Light Is On?

When your car hesitates to start and the check engine light is on, it can be a sign of a number of different problems. The most common cause is a failing battery or alternator. However, there are other potential causes, such as a faulty starter, fuel pump, or ignition system.

Battery or Alternator

A failing battery or alternator can cause your car to hesitate to start because it is not able to provide enough power to the starter motor. This can be caused by a number of factors, such as a loose or corroded battery connection, a weak battery, or a faulty alternator.

Starter

A faulty starter can also cause your car to hesitate to start. The starter is responsible for turning the engine over, and if it is not working properly, it will not be able to engage the flywheel and start the engine. This can be caused by a number of factors, such as a worn-out starter motor, a faulty solenoid, or a damaged starter drive.

Fuel Pump

A faulty fuel pump can also cause your car to hesitate to start. The fuel pump is responsible for delivering fuel to the engine, and if it is not working properly, it will not be able to provide enough fuel to the engine to start it. This can be caused by a number of factors, such as a clogged fuel filter, a weak fuel pump, or a faulty fuel pump relay.

Ignition System

A faulty ignition system can also cause your car to hesitate to start. The ignition system is responsible for providing the spark that ignites the fuel in the engine. If any part of the ignition system is not working properly, it will not be able to provide the spark needed to start the engine. This can be caused by a number of factors, such as a faulty spark plug, a worn-out distributor cap, or a faulty ignition coil.

What Should I Do If My Car Hesitates to Start and the Check Engine Light Is On?

If your car hesitates to start and the check engine light is on, it is important to have it diagnosed by a qualified mechanic. The mechanic will be able to determine the cause of the problem and recommend the appropriate repairs.

Here are some tips for diagnosing the problem yourself:

Check the battery terminals for corrosion or loose connections.
Try jump-starting your car.
Check the starter for any signs of damage or wear.
Check the fuel filter for any signs of clogging.
Check the spark plugs for any signs of wear or damage.

If you are unable to diagnose the problem yourself, it is important to have it diagnosed by a qualified mechanic.

How Much Will It Cost to Fix My Car?

The cost to fix your car will depend on the cause of the problem. However, here are some general estimates:

Battery replacement: $100-$200
Alternator replacement: $200-$400
Starter replacement: $200-$500
Fuel pump replacement: $200-$500
Ignition coil replacement: $100-$200

It is important to note that these are just estimates, and the actual cost of repairs may vary depending on the make and model of your car, the severity of the problem, and the location of the repair shop.
