I have a 1998 Pontiac grand prix it will crank but won't start. Has no fuel pressure and no injector pulse. It has spark. I replaced fuel pump, filter, relay and fuses. What should I do? far as I know the injectors are working it sound like we're getting fuel I think we got spark it just won't start

Was the MIL indicating?
It could be a fault with the cam sensor if the injectors are not pulsing.

You can't test the CMP sensor. You can only test the voltage from PCM to the sensor.

Are you still missing fuel pressure and injector pulse? Did you test the fuel pump operations??

Hooked a hot wire to the fuel pump and had fuel pressure but still wouldnt start. I also replaced ignition control module. Somebody told me it could be wiring in the steering column

There are so many possibilities and it does not matter what anyone says. We need information to get the problem resolved.
At injector connector, do you have battery voltage at one of the wire with ignition switch turned on and while cranking?
Does spraying starting fluid into the throttle fires up engine?

If you have a noid light, disconnect an injector and attach the noid light over it to test if it pulses.

Did you perform the test and come to the conclusion that the injectors are not firing?
Did you try if starting fluid works?

When you turn the key to the on position without staring the engine do you hear the fuel pump running in the tank?

Also can you confirm the absence of injector pulse hear is a guide.
