95pcm in a 96 car

I was thinking bout the little inline fuse. The car cranks, just no spark, and I don't think the fuel pumps kicking on either. Unless I jump a power right to the wire, would that one wire do that?

That wire is battery power for the ECM and I can't tell you what the PCM is doing on the inside.

You could check the fuel pump relay wire coming out of the PCM to see if it is sending power to the relay.

Also not sure on the VATS/Security side of things and if any of that could be telling the PCM to not turn on the pump.

Do you have this connector? It would be red, and will turn the pump on with 12V straight to it. That will tell you outside the PCM is good to the pump.

I ran a power to there the pump kicks on and primed everything

Does that mean then all the wire is right up the PCM and stuff. Or does that jumper wire run directly back to the pump?

Also bud just to be clear, that last wire schematic was of that one wire harness/plug that's also in the picture here from shbox.com

That powers the relay to power the pump, so wiring and everything east of the PCM is good for fuel.

Yes, the shbox was of that plug on the last schematic. My last schematic post puts the two pics together. The top connector and chart is the 96, and the bottom half of the chart starting again at "A" is the 95.

So did you jump 12V to the "D" pin?

Nah. I'm all finished for today. I'll try it first thing tomorrow I'm anxious to hear her purr!

Me too! Let me know how it goes. If that jumper doesn't do it, I will look over the schematics again and see if there are anymore "power" wires missing or different.

Awesome. Thanks! I'm gonna check it out here in a little bit. Just went down to start the kerosene heater, and let it warm up a bit.
So far I haven't noticed any differences really. The cruise cable is a little different where it connects to the bracket that holds it to the intake manifold. It will stay but just don't "lock" quite like it should.

I'm not even sure what made me look at those wires there but I'm glad and hope that's the issue! I've done a few engine swaps but this is my first LTx.

Kinda off topic, is ur Z arctic white? I think the paint is to far gone on most of the t/a I got from Chris so I'm gonna be repainting it eventually. I'm staying white gonna probably do arctic white, 96t/a it's called something else but it's the same code. I was thinking bout doing the roof black also I like that look breaks up all the white.

I snagged that wire outta the 95 and run it right to the bat+ right where they split on the fender. Still no power. I'm putting the driveshaft, torque arm on tight now so I'm gonna look for any ground or something maybe I missed.
