last post before going to the dealer

Alright i have done everything i can think of. New fuel pump, filter, and fpr. I have good fuel pressure 45psi. Once i took care of that i figured the car would start for sure (keep in mind it was left to sit and hasnt started in 3 months) but it didnt. So i put knew plugs in because they were all wet with contaminated gas and i also drained the fuel tank and put fresh gas in the tank. So now i figure for sure it will start... but it didnt. Then i go to read the codes again (last code reading only left me with a map sensor high circuit input) and this time i get a bunch of other codees popping up. The map sensor problem is still there but know i have the engine coolant temp sensor circuit high input and it also says that injector circuits 1,4,6 and 7 are all open. What the hell. My computer must be shot. All the injectors have voltage going to them but the above 4 do not pulse. How can this happen all of a sudden. I didnt get these codes before.

I should also mention that my scanner says the my timing went from -10 degrees to -20degrees. What the %$#@. Anyone know what the correct timing is supposed to be.

The PCM supplies a 5 vdc reference to both the Intake air & Manifold pressure sensors, since both of these sensors are reading screwy, you could have a bad reference supply within the PCM . I would check to verify a steady 5 volt reference is present.
