68 Camaro-LS1 Painless Wiring harness. Put over 10k miles without a problem. Last week it died while driving down the highway.
Turn key on and fuel pump doesn't cycle. Engine turns over but no fire. Jumped fuel pump and it works fine. Checked all fuses/relays and everything seems fine.
Scanner will not communicate with the computer.
Any clues where I go next? I didn't do the install and am going to look on Painless website to follow the schematic. I would assume the computer either isn't getting power or isn't putting out any power? Starting to scratch my head as I just new it was a fuel pump relay/fuse.
Thanks for any help.

Well, their kits have 8 fuses and 2 relays, are those the ones you checked, or did you check your stock setup?

There might check the fuseable link off of the starter going to the car, if that is still intact from the stock wiring....that could be it.....it all depends how someone else wired up your car.


I hate working on wiring that someone else did....have fun.

 

I'd check all the ground wire to make sure that's not the problem.

 

Lowerdd-Thats a cool looking Imp.

Thanks for the help. Downloaded the painless harness and traced the 12V power supply wire. Turns out it was spliced into the old resistor wire. Re wired it with a constant 12V source and its working great now.
Though I have to tell you that a Ford guy fixed the car.

 

A Ford guy fixed it? Well sure he did ding dong..........he's had plenty of practice!! LOL.


Oh, and thank you.
