I just installed a Fast bank to bank & harness that came out of a friends car a while ago running! Now in my car I have a volt feed back problem, the volt lite glows with car off & car stays running with the key off!
 
IN NEED OF FAST HELP

I forgot to mension when I reinstalled the stock ecm all the issues went away!
 
I would bet theres some short in the harness. I would ohm it all out with everything disconnected. i think theres a pinout in the fast help files, if you have the new version of the software
 
Perhaps you "T"ed into the injector power feed instead of cutting the wire and suppling the power solely from the FAST.
 
NEED FAST HELP

No I cut the lead from the stock ECM, I wish it was that easy! Has anyone had an issue like this before? I think it's got to be jumper harness,but it worked in a friends car prior to my install? When I switch back to stock ECM all is good again! THANX for any help!
