The ICM or the Ignition Control Module is the brains behind the spark plugs. The ICM tells the spark plugs when to fire and lets the engine know when gas needs to be released for proper engine ignition. Sometimes if your ICM is out or going bad, you may be able to start your motor up nicely once and then when you turn it off it may not start back up but it rarely ever goes out. mechanic for 10yrs
the diesel engine. it takes one ignition to start, then it runs off of (autoignition) ignition from heat caused by high compression. compression ignition (autoignition) causes ignition to happen a little earlier than spark ignition engines (gas engines) which is less vulnerable to risk of engine knocking or wasted power when dealing with high compression. -maddmatt
It may stall and refuse to start if the ignition gets wet.
if the battery isn't dead, or the terminals loose or dirty, number one cause - ignition problem (spark plugs not getting electricity)
If you have a "check engine" light on, start with having the codes read. A misfire code can tell you which cylinder or cylinders are having problems. A misfire could be the cause of your engine vibration.
What happens depends greatly on which module fails. If the engine control module (computer) fails it may cause the engine to run poorly or not at all. If the ignition module fails the engine won't start.
start the engine if it runs its good
no..if its bad your car wont start
The ignition control module for a 1995 ford f150 is an important part of the drive train. If the module is failing then the engine will run erratically or not start at all.
A bad ignition module will cause a no start situation in a vehicle because the needed spark is not created. It is responsible for telling the distributor when to fire.
No. It will cause it to not start but it will still turn over.
look at the ignition module. a known trouble spot.
Yes, a bad coil will prevent the ignition from firing and the engine will not start.
dead battery, or a bad ignition control module inside the distribureator.
A bad ignition coil will cause your engine not to have any spark. Without any spark the engine cannot start or run.
the two most common no start when hot causes are fuel pump in your fuel tank and loss of spark ignition module
