Resolved 2G No power to PTU

[chrisman287]

I’m having a similar issue. Tried a different coilpack and PTU. Went to cut/extend PTU harness so that I could bolt it to the intake manifold and white wire just fell out of the connector. De-pinned it and soldered a new wire onto the pin. Put it back together, cut/extended and bolted to the IM and nothing.

I was thinking MPI especially since I’m 95 I know they’re iffy but I have fuel I can hear the pump no problem with the key on and if I spin the CAS by hand. Part of me thinks it’s the ECU.

I just bought another ECU to test as well as a different coilpack and PTU. Hoping all three together will solve my problem.

Well my ECU worked fine on another car so I ruled that out. Another PTU or coilpack didn’t help. Might just try another engine harness.

It's time to restate exactly what your problem is and what all you have done to diagnose it.

You can delete this. I had a similar issue to the guy in the post but ended up being my CAS adapter harness. The white wire had no continuity so once that was fixed it turned over.
