Resolved 2G No power to PTU

[v8s_are_slow]

Replaced engine and then was only running on 2 cylinders on first start. Trying to diagnose and now for some reason, no power to the PTU at all. PTU has been tested and is good. Just no power going to it. Checked fuses under the hood. Fuel goes to the rail though so assuming MPI isn't the issue.

Where does the power wire go to on the other side of the harness so I can check for continuity? Thanks!

It sounds like the wire that was bad was the one from the MPI circuit and it's shared by a large part of the engine bay. Make sure the rest are getting power as well.

Yeah, everything else is getting power. But not sure if the noid light isn't flashing when I spin the cas housing because it needs the crank as well.

I guess if I put it all back together again and it doesn't work, it's back to the drawing board.

The one wire that got replaced due to being a bit too toasty in an engine fire a few years ago fixed my issue. Just have to button everything up now. Shew!!!

Guess this post can be closed up now. Thanks y'all.

Didn’t realize you were Scott Laird until now. Just started watching your tuning videos. Trying to get my car to idle.

Glad to see yours is up and running
