93 grand am no start

Someone please help, 1993 grand am GT 3.3 liter will spin over like mad but will not start. what could be wrong, changed ign mod and coils still no start. fuel pump working can here it pump up and quit. put gauge on fuel line pumps up to 50 psi is this good. again please help.:runaround:

Well is your plugs firing at all ?
Are you injectors firing properly ?

How was it running before this ?

Sounds like you might have internal issues... 50 psi is good pressure.

Plugs are not firing at all, the injectors do not seem to be working as well. I pulled out 2 plugs and they look like they are white and very clean burning.

Sounds like your crank shaft position sensor is bad.
Its located behind the crank shaft pulley.

You can check your ODB I for trouble codes to see if thier are any for the crank sensor, may not be though.

Here is a thread for checking ODB I dtc's if you dont know how.

Good Luck

I have someone picking me up one as we speak, will let you know if it pan's out, thanks for your help. ps could it be the control module.

If you replaced the ICM then it shouldnt be the problem.

You can test the crank sensor...

Using Volt Meter, backprobe the sensor signal terminal (A) with the positive lead , and backprobe the sensor ground terminal (B) with the negative lead.
When cranking the engine you should have approx 5 volt signal pulse, if not the sensor is probly bad.

Also check the interrupter rings on the crank pulley make sure they are not bent or damaged.

Good Luck
