Okay, here's the deal. One day I started my 90 SC up and started to drive down the street. It bucked hard a few times and then died. I tried restarting it and it seemed like it would almost turn over some times, but at others it felt like the engine was fighting the starter. I checked for fuel pressure and spark and had both.
Not wanting to waste time with redundant posts, I checked the forums for similar problems. I see that if you try to start it and the upshift light stays lit, then it's the crank sensor. So, I ordered one of those and replaced it along with the cam sensor. Still won't start.
I used a volt meter to check the wires going into the DIS module to make sure that both the cam and crank sensors were sending signals (voltage was changing as the engine was cranked).
Confused, I checked for spark again, and there now was none. Upshift arrow still stays lit when cranking.
Checked the engine codes and it gave me code 14 if I remember right (Profile Ignition Pickup, I'm sure of that). So many people have had success by replacing the crank sensor I was sure that was it, but obviously not for me. Anybody have any clue as to what I should check next (and how)?
