2001 Pontiac Bonneville Cam And Crank Sensor Codes

[Steve]

Pontiac boneville 3800 series 2. There was a code for cam crank sensor. I replaced crank sensor and wiring harness to crank and cam sensor...the wirning harness was from the junk yard the crank sensor was new.
The car dies out, i took it in to a shop and this is what they said, this car has codes for for cam and crank sensor also has wire harness to it if we wiggle the harness car dies customer has been told we would like to replace cam and crank sensor and then wiggle harness..when i pull up on the the harness the car will start if i wiggle the wires it wont start. it like i'm pulling up on the coil pack or the thing the wires are pluged in too it will start.

It seems you probably have a partially broken wire inside that wiring harness somewhere, and as you (or the other mechanics) pull or wiggle on it, you get different outcomes. I would hesitate to say that a junk yard harness would be a good choice. You might want to at least try a brand new harness from the dealer, before replacing any other sensors again. That would probably take care of your problem.
