1999 Malibu LS 3.1 L Style M OBDII

Previously...
-Dim headlights
-Random ABS, Brake, Theft Light, but always off at next start up
-Sun Roof doest always like to close
-Gas gauge works until your down to a half tank, then it starts to go back up instead of down until its empty, then it shows empty
-Sometimes when you turn on the a/c, the gas gauge jumps to full and stays there until you shut it off
-Check engine came on once, but was off at next start up
-occasionally had to tap gas at startup

And then...
-Driving home, turned right --car died, no warning lights, or funny noises, just died.
-Initially restarted, but it was rough and sounded like it had a timing issue.
-Towed it home and now it will crank but not start.

-tried ether, no fire--but you can hear the fuel pump
-spark plug test shows no spark
-checked all fuses inside and underhood
-all 3 coils and coil wire were checked
-changed crank position sensor, no change
-changed ignition control module, no change
-changed igntion switch, no change
-checked the only known fusible link by the alternator, its good
-checked for continuity and connection issues around cps, icm, and pcm
-did the relearn procedure for the computer

It is not passlock, the security light does not flash. Tried to reset it anyways, and the light never went off

The multimeter died after checking the igntion switch--coincidence??

SO whats left??? Why wont my car start????

At this point you could check the white and pink wires inside the dash behind the radio for power. Might as well check the orange and brown acessory wires too.

You need to see if fuel flows and spark sparks. so:
1 - disconnect the fuel line and turn on the key to see if fuel is flowing (don't assume);
2 - check the spark plugs (1 or 2) at crank with an insulated hol;der and someone turning while you check.
3 - then go on to the next steps.

Sounds like to me that if it ran rough, then it could be a timing belt issue or something.

it definitely has fuel---i did have him check those wires--previous owner had a new stereo put in--i was hoping they just messed something up, but it all checked out. we returned the new icm and are getting a replacement monday, from what ive read, and eveything thats been checked and double checked, its almost gotta be that or the pcm
i found a very good sight explaing how all of it works
