well i finally got the EJ22 into my EA82 car and got no ground for the fuel pump relay:mad: . light green wire at relay to ecu is supposed to be ground. all ground wires were left in the harness and connected but not getting a fuel pump run and no spark either:mad: . worked on it til 1am and am very frustrated..:-\ ..any clues would be greatly appreciated. any info from factory manual would help i think

 

thanks in advance:slobber: ,

figured out that i had the fuel pump wired wrong in the project car:banana: :banana:

 

had the factory relay cutting fuel and the cam timing was off

 

 

RUNS REALLY GOOD NOW:headbang: .....HAVEN'T HAD IT ON THE STREET YET BUT IT RUNS AND MOVES UNDER IT'S OWN POWER:banana:

Wish I had some great advice for you...

 

When I did my wiring I ran 4 or 5 ground wires from all the points that needed to be grounded off the ECU and harness straight to the negative battery terminal. In other words I didn't really trust that they were getting to ground through the harness.

 

There were two wires that were vaguely labeled in the Chiltons diagram, I traced them to the ignition switch in the donor car. I believe one was powered up in ACC, the other in start. I wired those in directly to the EA81 ignition switch.

 

Are you using a Chilton's manual for the wiring diagram? They aren't great, but they will get you there. I can upload a copy of it and post a link for you if you still need it.

 

Don't lose heart, it really doesn't take much to get these engines going, whatever it is you'll figure it out. Just start going back over it, wire by wire (not fun I know, but you'll get it). There is literally nothing like hearing your EJ beast fire up for the first time!

That is the gospel truth.

 

Keep at it.

While working on stripping my EJ harness down, the temptation to chop all the wires 6 inches from the ECU and doing it from scratch was almoast overpowering. It can be soo frustrating tracing out each of the wires.
