No spark - weird voltage readings. Any help?
Putting the car back together. Shop blew the car apart and f-ed with the wiring. Good times. It ran fine yesterday, now it won't start. No codes, no spark leaving coil. The tests on Shbox are a bit confusing, but this is what I have:
Car is a 1995
At this point, I am not sure what is going on. I tested KOEO at the opti harness (ICM disconnected):
Pin A: .5 volts
Pin B: .5 volts
Pin C: 0 Ohms to ground (key off)
Pin D: 0 volts / .2 ohms to ground (key off) This goes to B3 at the PCM.
Checked fuse - good. Checked continuity to B3 at the PCM: Good. No power out of PCM at B3
Pin A: 11.4 volts
C: o ohms to ground key off
D: 11.4 volts
Any ideas, folks? I am stumped.
