MPFI swap: No ecu or fuel pump power

[thurmanmerman]

Was working out problems with a couple codes that my ecu was throwing and took it for a test drive. Ended up dieing completely out of no where. Checked the main relay, grounds and fuses. Cannot figure out whats going on. Ive looked into the wiring and that seems to have checked out fine. Are there any other fuses not in the engine bay box or under the dash that would cause this problem?

getting power everywhere else in the car?

Cut the engine harness

look where the car came from lol

cut in half!!

[thurmanmerman]

For real. I need to get this figured out.

Get your multimeter out. Make sure all of the wires that should have power have power, if the wires are good all the way to the ECU plug, maybe the ECU popped??

what ecu is even in there...

PM6

lol

[harm]

sounds a lot like when my ecu suspiciously blew - for no reason on the day the landlord kicked the neighbors out..
starter cranked away, no power to the fuel pump, checked the main relay, fine, checked for a code at the ecu.. no power no nothing.

put in a new one, fixt.

btw does anybody want a pr4.. cheap..?

Unless he went stealthmode on it and put PM5 guts in a PM6 case. Its a PM6.

Got it to start last night but only after jumping the main relay with 12v power. Fuel pump primes and ecu comes on.
