I am having a problem with my Classic FAST system on my Buick. I am almost 100% I have a bad wire somewhere but can't find anything wrong. I sent the ECM to Craig Smith and he could not find anything wrong with it. I also got a new Caspers wiring harness adapter. So that should be able to rule those two out. All three of the lights are on on the adapter harness box will light up when I turn the key on.
When ever I turn the key on the cooling fans come on. If I try to connect my laptop to the the ECM it just says no ECM found. I would like to ohm the wires out and see where my problem is. But I can't find any wiring diagrams that go from the factory ECM harness to the FAST ECM. Does anyone know where I could find these?
Thanks,
