Re: 97 k1500 no start, failed PCM?

Thanks for the quic replies guys.

c3-#21 -> ~12v Key off
c4-#18 -> ~12v Key in run
c4-#13 -> ~12v Key in run

The power from the ECM-1 fuse seems to go to ground when the key is off, but shows voltage when the key is on. That seemed kinda strange too me as well.

All the guages, seem to work as well. The gas guage picks up when the key is on. So it seems that there is some kind of ground thing going on. I;m just unsure how to help narrow down the search. I'd hate to have to rip the entire harness out of there.
