improper voltage on wrong wires to CAS with AEM
 

Alright, it ran fine when I parked it in October, I took it all apart and redid a bunch of stuff, but other than putting the wires through a different hole in the firewall, nothing about the harness changed.

But now it wont start. It's not stat syncing, so we checked all the wires to the cas, and according to this:

pin 1 (Larger)Black Ground
pin 2 Red +12v Power
pin 3 White TDC (to ECU pin 22)
pin 4 Black Crank Angle (to ECU pin 21)

What I have is wrong. On both cam and crank signal wires I have 5 volts, and nothing on the others (or 5 on the power wire, it's all a blur right now).

With the big plug unhooked, I tested voltage at the ecu and both signal inputs for the CAS showed 5 volts, I didn't look for 12v for the power wire, I'll get on that tomorrow.

Anyway, the car's ready to start, just have this problem.

Did you have to cut any wires to re route them? I would do an ohm check from the ecu connector to the cas connector, there has to be a cross in wiring some where.

The only thing I lengthened was grounds, I believe, and I'm fairly certain I didn't touch any of the wires to the CAS. But that's one thing I'm going to check tomorrow after work. I just hope I don't have to pull the whole harness out.

got it, just needed a hint from the AEM tech support guy. He asked if there was 12v, and I checked again and no there wasn't so he said jumper it to the battery. Guess what happened next. Worked fine. Thanks to everyone who helped.
