I have a 1990 325i with the m20 motor. Recently it started getting harder and harder to crank, and now it will not crank what-so-ever.
I have replaced the main relay.
I am NOT getting spark from the spark plugs, but I am getting spark from the Ignition Coil.
I am getting fuel to the engine because the spark plugs smell like gas and gas squirts from the engine when I removed fuel line.
The distributor cap and rotor are in good working condition.
Other than that I can't think of anything else that would cause the car to just stop cranking.
OH and the starter is turning the engine but the engine isn't coming on.
The only other things I can think of is the ECU.
Thanks for all the help,
Jeff
Ignition Module? Please explain.

Check the ignition module.
