Chevrolet Repair: chevy venture will not start, mass air flow sensor, mass air flow

Question
I have a 97 Chevy Venture that will not start.  I noticed there was not any power to the fuel pump, so   I replaced the computer.  Now there is power to the fuel pump but it was not coming on.  So I dropped the tank and replaced the fuel pump.  The van will still not start.  I also replaced the egr valve, mass air flow sensor, fuel filter, but it will still not start.  All fuses and relays checked out good.  The new fuel pump and regulator works as the manual states, fuel pressure is also good.  Yet, the injectors will still not spray.  The van will start if you spray gas in the intake.  Any help would be appreciated.  I personally think the dealer sold me a bad computer, or it is something with the alarm.

Answer
Hello Matt, I would install the old pcm and try to start the van. The NEW pcm needs to be programmed for it to work, and I haven't seen that many bad pcm's. I'll bet your problem with the no start was just the fuel pump, so give it a try with the old PCM.

Have a Great Holiday
