Will not start
2002 firebird 3.8v6
My son'* car wouldn't start a couple of weeks ago and had a code 1589 I think. It would turn over strong but not start. I reset codes and it started. Yesterday it did it again and wouldn't start no matter what we tried. He has had trouble with the security system but this seems diferent. The code said no communication between throttle control and PCM. Any ideas?

Update
Have 50 psi fuel pressure, no signal to injectors, no spark. Have no voltAge at pink wire at ICM. Where does this wire feed from? We heard clicking noise at throttle control and got 12V at ICM. It started twice (low power) then wouldn't start again.

Is the Security light flashing?

Have voltAge at all the fuses. Borrowed a scanner from a mechanic and cleared codes. Now it starts. We think it'* in the fuse box because we had power at all the fuses but no power at the ignition module.

Still have problems.
We have a wiring issue. Where can I find a good wiring diagram for ignition, BCM, etc? Trying to see how the wire at the ignition module runs. Have 12V there and ignition switch at times. Seems to be a bad connection some where.
