No fuel/pulse, but have spark.
I believe I have narrowed down my problem to the ECM, but I wanted to verify it first because my ECM just got back from ECMtuning a little while ago and I didn't want to send it back to them for nothing. 1992 Galant Vr4. Was running fine. We swapped the cruise control system back in that had previously been removed and while that was taking place the alarm went off and we had a hard timing turning it off. I only mention this because in case there is some connection I am unaware of, I wanted to state it. Since then the fuel pump is not turning on and we have no injector pulse. The fuel pumpdoes not have power going to it. I have tested the MPI and harness and it is ok. I also checked the majority of the fuses, specifically the ones that could be related. I am a high school shop teacher and this is a class project. I'm always aware of the X factor of teenagers, so I am trying to make sure I don't overlook something stupid they might have messed up. As far as I understand the CAS would create a no spark scenario, so it should be good. Any other tests? I have looked through the FSM and have no seen a troubleshooting flow chart. Which was surprising to me. Again, I did follow the diagnosis procedure for the MPI and harness which Alldata had and it concluded that if everything passes that it was an ECM problem or an intermittent problem. And since the problem is constant, ECM looks highly likely. Anyway, last note is that I did pull the ECM and it passed a visual inspection. I believe the ECM for a GVR4 is different than a regular 1g because of the MAF flow being different. Otherwise I'd try to find one to swap with. Any other ideas?
