This time I'm stuck. For the last week the car has been getting harder and harder to start. Now it will crank forever and not start. I replaced the fuel pressure regulator diaphragm because it ripped and let a bunch of gas flood the plenum through the vacuum line. I also just replaced the ignition control module because it had a code 42. It has spark, the injectors are firing but it won't start. If you give it about 1/3 throttle it will sputter but that's it. Any ideas?

 

check your fuel pressure, sounds like the fuel pump is bad

 

when I turn they key to "run" the pressure is about 40

 

injectors firing or not, you must ohm check those multec injectors. if any are below 10ohms call FIC (www.FuelInjectorconnection.com) and get the bosch 3 injectors.

 

I already have the Bosche III injectors from FIC. The Multecs died last year.

 

then you have to look at ICM, fuel pump, fuel pump relay, etc

 

I found the problem. When I pulled the distributor cap to put in the ignition module, I put all of the plug wires back 1 spot off going all the way around. Thanks for the help anyway guys.
