1991 Saturn SL2 Engine will not start

The original PCM went bad a few years ago and from I can tell it was the original. I replaced it with PCM #2 in April of 2009 and I bought it from a salvage yard it was supposed to be from the same year and DOHC 1.9 auto.
PCM #2 I plugged it in and the car fired up and ran fine for a year. April 2010 the car just quit running while driving down the road. It quit a few different times of the course of a few weeks. I would let it sit for a day of so and then it would sometimes start. The last time it quit it has never started again.

I purchased PCM #3 from a salvage yard as well and hoped that it would just plug in and fire up like last time. The car has not ran since PCM #2 quit.
I still have all three PCM's and have tried all three but the car will not run.

I will have Dan prime the car to see if it will indeed run.

Hello,

Well Dan somehow rigged up an external fuel supply to and the car ran. While it was running he checked most of the vitals and everything checked out as if it would while running. If he took the fuel away and tried to let it fuel itself, if would not run. The fuel pressure was around 40 psi. There is an issue with the injectors and Dan wanted me to email you to see if you had any suggestions. He was maybe going to take a look at the injectors to see what was going on there.

Thanks

Dan had gas in plastic bottle and the gas was sucked through PCV hose. The injectors were not spraying any fuel and we have 40 psi fuel pressure at the rail. The car will run great if given fuel but when you remove the secondary fuel supply and try to run on its own, it will not start.
We did not have pressurized fuel, we let it draw in though the PCV hose instead of through the fuel rail.

Dan seems to think that for some reason the injectors are not pulsing so what do you think the problem is?

Thanks

I have power at the pink and black wires at the injectors, power on both sides of the connectors (to the injectors). I do not have flash at the dark blue wires while its cranking.

When you unplug the connectors at the injectors the pink/black have power and the blue wire has power. While cranking the dark blue wires are constant power and not pulsing. Should that wires be pulsing a ground signal to control the injector?

The computer or whatever is not working is not controlling the ground side of the injector.

What are the odds that I would have three faulty PCM's currently. Could it be possible and how can I test to see if that is the case? Should I consider buying another PCM to see if it would start?

We plugged a scan tool in and I think the only code that came up was 44 or 45 lean fuel mixture code.

Thanks

I was talking to a Saturn salvage yard and asked about my problem and they mentioned that it could be a fuse issue. I am in the process of checking all of the fuses in the entire car and also disconnecting the aftermarket car stereo. They said that sometimes aftermarket audio is to much for Saturn's causing circuit overload. Does that make sense to you?

I am going to work on it tomorrow and will test the blue wire for power with and without the fuse. If I still have power in the dark blue wire, what is my problem? Bad PCM? If the power goes away what would be my next move?

Thanks
