Usually an intermittant no start is caused by a fualty Crankshaft Position Sensor. Best way to verify this is to check for spark during a no start situation. If you have no spark at the coil towers then your CPS is bad and needs to be replaced
Ignition module bad.
No spark can be as simple as a ecm fuse blown, a bad ignition switch, defective ignition module or a bad coil.
YES! the spark plug ignites the fuel mixture and causes combustion
Yes. If the ignition is malfunctioning, the spark plug will not ignite. A bad ignition module, a bad spark plug or a bad plug wire are the most common causes of that (besides a bad battery, of course).
No, spark plugs do not cause ignition in diesels. The fuel compression causes ignition
the ignition control module could be the problem
YES! the spark plug ignites the fuel mixture and causes combustion.
A BAD CRANK SENSOR WILL CAUSE NO SPARK AND NO PULSE SIGNAL TO FUEL INJECTORS a bad ignition module will cause no spark its located under the ignition coil trio pack
Check the ignition module in the distributor.
fasopoas it crap you do do
Ignition timing, spark plug or wire, internal engine,
Crank sensor has failed,Ignition control module (ICM) has failed,Bad ignition coil pack,
The Ignition Coil is the one that cause misfire or Spark Plugs
A 'spark ignition ' engine is your regular gasoline engine as opposed to a diesel, which is a 'compression ignition' engine
There are basically two types of spark ignition engine. They are the diesel spark engines and the petrol spark engines.
Wet weather causes everything under the hood of the car (even the spark plugs which create ignition) to cool down which causes start up problems. Ignition can only happen at a certain temperature.
Ignition module, cam senor, crank sensor or bad computer
No. The coil provides the spark and the module tells the coil when to spark.
poor spark plug gap bad wires or weak coil or bad spark plugs
wires are worn and need replacing
When the piston compresses the fuel-air mixture, the spark ignites it, causing combustion
Common causes include spark plugs, ignition coil, fuel injector, wiring, internal engine problems, and computer malfunction.
The ignition module is under the ignition coils The coils are bolted to the frt of the transmission housing. Follow the ignition wires to the coils The coils are bolted to the module underneath The module control spark to the spark plugs. It sends the required signal to the coil as to when to fire t then fires and "sends" the spark through the ignition wire to the spark plug
