I finished putting my motor and tranny back in the car last night after rebuilding the head with new valve seals, single install, and a few other things.
Tried starting the car and I get cranking but not starting. My ECU does not get any power and it seems to be a problem at the EFI relays. When I jumper the EFI Relays terminals 3 and 5 together with pieces of wire, the ECU gets power and car starts up fine (with fuel pressure quickly decreasing since it doesn't seem to supply power to the pump after cranking). Since I have a 2nd stock pump wired up on a separate connection, I can turn that on and the car runs fine.
Anyone have good knowledge on how the EFI Relays are triggered? I tested the relays and they work. The problem is that there is no trigger signal sent to the relay once the key is turned.
I checked to make sure all my grounds are firmly connected. Unfortunately I didn't pay too much attention while disconnecting the grounds. Are the 2 ring type connections coming off the negative battery terminal suppose to 1 go to the chassis and the other bolt to the block? I vaguely remeber this when I was doing the pull.
On a side note, I don't know if this is a related or separate issue, the alternator is not outputting any voltage when the car is running. I tested it by probing the big positive terminal while the car is running. Voltage just slowly drops once I remove the jumper cables.
Thanks for any help, suggestions, or ideas.
