What can cause no spark?

What can cause no spark?

Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.

What would cause no spark from distributor?

A Bad Rotor Or Distributor Cap (cracks or carbon tracks that are allowing the spark to short to ground). Often the distributor cap is suspect. Consequently, it could short out the coil voltage and cause a faulty connection inside the terminal of the distributor cap. The result is a misfire in the spark plugs.

Why do I have power to my coil but no spark?

There are a few reasons for no spark, new coil pack could be defective, crank sensor, ignition module or bad wire in primary circuit, faulty ECM/PCM. You may have to have a good technician have a look, diagnose and estimate repair. Second link gives detailed instructions for testing and diagnosing coil pack.

What would cause no spark or fuel?

If there is no spark or fuel, then the first thing I would do is check the vehicle’s fuses and relays, particularly the EFI main and ignition relays. It may be possible that one of these components has failed and is cutting off power to the vehicle’s ignition and fuel systems.

What does it mean when your engine turns over but wont start?

When your engine cranks but won’t start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter).

Can an ignition switch cause no spark?

No spark is one of the most common causes of a no-start condition. It’s the first thing I check for. The igniter or ignition module, the pick up coil or crank sensor, the cam sensor, and the ignition switch are included.

What does it mean if my car turns over but wont start?

Will a bad cam sensor cause no spark?

If the camshaft position sensor is malfunctioning, the computer may not be able to determine the correct time to fire the ignition coils, and there may end up being no spark.
