Hello everyone. I'm new to Cadillac and Northstar ownership even though the car is very old. I have a 2001 Seville SLS with the code P0386 showing up even after I replaced both crank sensors and the cam sensor. I had codes P0385, P0386, and the code for the cam sensor. All but P0386 went away and since that code signifies an open circuit I decided to check the harness. The thing is, I can't find any specific diagrams and from what I looked through the harness looks good. Does anyone know where the ground(s) for the CKP harness are? And how is anyone supposed to use a multimeter on the connector? My probes are too big. Some more info: the car still wouldn't start after replacing the sensors. I cleaned the IAC, the car started great. After about 15 minutes of idling the car would stall again. Then after a few days the no-start came back. Thank everyone in advance. Hopefully I can solve this problem without having to resort to the dealer - it's a 1500 dollar car, I really don't want another 1500 into maintenace
