98 Catera Crankshaft Position Sensor Replacement - Cranks Won't Start - Page 4

After having the car sit for almost 9 months because I just couldn't look at it anymore (because it just wouldn't keep running once operating temp was reached). I decided to go out and purchase a CPS (Crankshaft Position Sensor), paid $110 CAD for it, they had lots in stock because they said it was a common problem. I took almost 4 hours from start to finish, but ya baby! It has been running, and running and running without a hitch now for the past month. When I pulled the old one out, the wires had been pinched in the heat shield, when it got too hot everything expanded and shorted the sensor, causing the car to shut down. Re-routed the new one around the problem area, and kaabam! Life is good again. Once I purchased the CPS, that is finally when I got some answers from the dealership on the problem, not before, go figure, if they figure you actually may know the problem already, they are willing to help, otherwise, they will let you squirm and pay big bucks on diagnostics!!! Not very nice I would say, would you?

Yeah, so after running beautifully for over a year, that damn CPS goes on me...A bullet that I though I was going to be able to dodge reared its ugly head. lol. I guess my suspension upgrade will have to be put on the back burner. So the Cat will be sitting for the next couple of days while I wait for GM to bring the part in $85 is not bad. I may try napa to see if I can get it sooner. So for anyone thats done this themselves. Is it easier to access the sensor from the side or sliding under from the front?

I'm not 100% sure but I've heard Cam Shaft Sensor has similar symptoms. Only thing is, the sensor is 3 times the price of the Crank PS
