Electrical issues?

[1NASTYGN]

Having problems with car staying on. Sent out ECM to be looked at. Removed TRANSPRO and went back to Eric's chip thinking the problem was the pro w my e85 combo. Car started fine and now runs for about 5 minutes and abruptly turns off? Any guidance or similar issues happen to anyone? I am thinking it is the ECM.

You can check this connector behind the glove box for the pink/blk wire in it per this thread.

It powers sensors under the hood as well as the ECM and if it goes intermittant the car runs bad or usually dies.

It fixed my problem which sounded exactly like yours.

Search "glvoe box connector" for the another thread which has pictures in it, but it's right behind the glove box door with foam wrapped around it you can't miss it.

Will it restart right away ? Do you lose fuel pressure ?

it does restart and then shut off. I have the new E85 pump from racetronics

FP does drop off. Could it be the FP? Wiring or relay?

^ or the FP hose in the tank, or the FPR

Does the fuel pump run for a couple seconds when the key is turned on?

Try this. Make a small jumper wire. Unplug the fp relay on the passenger fender. Jump pin B and D on the plug. Start it up and see how long it runs.

The pump does turn on for a few seconds and then turns off. I am going to try jumping the pins. I will also check the crank sensor and oil pressure switch. I rewired the pressure switch and hope I didn't cross the wires

I removed the transpro and realized i have no maf translator. fml

 

[TurboBuRick]

What kind of maf are you trying to run?

Why not use the tpro?

 

[1NASTYGN]

Installed the maf translator and fired car up. Car starts and runs while I am warming up. once I let go of the throttle, it abruptly shuts off? ECM?
