so i have no spark all the sudden on my 1995 2.2L cav i replaced the coils and still nothing,
I was told to check the crank sensor but i have no idea where it is what it looks like and what colour wires go to it can anyone help me ????? anyone think of n e thing else that could cause no spark bad PCM maybe?

Well you test your crank sensor. Simply crank your car and watch your RPM gauge, if it goes up at all while cranking than the sensor is working, if no rps at all then the sensor is bad.

A crank sensor also causes no fuel as well as no spark.




- 2004 Cavalier - 124k, owned since new

as for the location it is in the rear of your engine next to the coil assembly

anyone got n e other idea? i've checks, coils, crank sensor, PMC, engine grounds..... im running out of things to try

Do you have a theft light ON?

Did it just quit sparking when it was running or not want to start after it had been switched OFF normally?
