I'm having an issue with my sensor ground. The car is throwing 5 CELs; baro, iat, tps, cts, and knock. The knock sensor plug was ripped off at some point during my head swap, just haven't replaced it yet.
Some background for you... I got the car about a year ago, and shortly after did timing on it. Unfortunately I did not put locktite on one of the bearings /ubbthreads/images/graemlins/banghead.gif and bent over half my valves. The new head has behives and 272s and I used arp studs. I put everything back together and started her up, she ran for about 30 seconds then smoke came up from the ecu. I wish I had pictures of it but I didn't think to take any. It was textbook blown cap, to the point where there was no board separating the pos and neg of the cap. After the ecu went I tried two more and that's where I'm currently at. Both ecu's are fine, they display the same codes every time.
I have checked: both ecus (continuity between pins 17 and 24), sensor voltages, sensors, and continuity between the sensors themselves and the ecu.
No sensor grounds if the ecu is unplugged and with the ecu plugged in they all ground.
To put it lightly, I'm lost, at this point I have no idea what to check. I hope its something simple and stupid that I forgot.
Thanks for all the help.
