Again, new coil pack, new cam and crank sensor, new PCM, checked all fuel injectors, fuel pump works, got spark, turns over but no official start...
After all that work its terrible that something else goes bad however since you do get spark and fuel i would say crank or cam sensor but then if one of those goes bad it wont allow engine to turn over and would shut fuel pump off. so there is only one thing left to cause it you have a short in the harness somewhere maybe just a lose connection on the cam or crank sensor put dieelectric grease in all your connectors
ok well this is kind'a strange... it was #2 sparkplug went bad, not even a month old plug, and my car wouldn't start which I'm guessing is cause the cylinder was flooded, can't think of another reason only one plug would cause the whole car to not start thanks for you help!

If you have replace new cam sensor with no sparks and the coil are good putting out 12 volt, my guess would be the computer it self faulty. cam sensor sense the cam turning and send info to computer telling computer to disperse the charge from the coil pack to the plugs assuming relay, cam sensor, coil, plugs, and wires are good. make sure the cam sensor is put in properly and position.

You need to use a LED type test light for the injectors or a Bosch style Noid light for the injector. To test the cam/crank sensor signal you either need a scanner to read them or a lab scope to show you a signal. The pickup plate in the dist handles the injector timing, the crank sensor provides a RPM signal. They both feed the computer information for ignition timing. Good fuel pressure, injector activity(Noid), and good spark out of the coil. The coil is what I replace the most of.

The cylinders are numbered as on the spark pack you changed. You might have done better putting the seafoam in the tank as an injector cleaner. Not sure why you changed so many parts, you seem to know how to get the codes from test connector lead hookup and the blink pattern. You might also want to check the fuel rail pressure and the crank and cam angle sensors. Before replacing the injector, swap the #4 injector with the adjacent one and see it the code moves with the injector or stays put. If the code stays on #4, then check the injector wiring, if it moves clean or replace the injector.

Rob, I have gotten a new PCM just recently, ran 5 days on it, what would cause it to go bad so quick? And Oliver, I have change so many parts because it was at one point the crank sensor, then the ignition coil pack, then the PCM was the last issue, this issue looks to be the PCM again but I honestly don't know what would have cause the PCM to die so soon only after 5 days...
