Engine Problems
I have a 1994 3.4 v6 that ive done a lot of work on. Recently, the engine doesnt want to start. I changed the spark plugs and wires...the car ran for about three days and started to missfire. Now the car wont start, it just turns over. I replaced the ignition coils and checked the fuel pressure. Everything looks good. Any help would be really appreciated.

Possibilities:
Bad spark at the plugs (wires, coils, ICM, fuse #11)
Injectors not being pulsed by PCM (Use NOID lites)
No power to injectors , check the 2 injector fuses #9 & #10
Bad 3X Crank pos sensor, or wiring between sensor & PCM
Bad wiring between PCM & ICM
No power to PCM, fuse #11 in instrument panel fuse block
