Thread: Need help with 2004 pontiac grand prix gtp supercharged

I've been battling this issue since November of last year and I'm out of ideas of what could be wrong. At first my car would stall after I would come to a stop without any warning, then when I started it up and shifted to reverse the car shut off, now where it won't even turn over anymore. I've changed the fuel pump, fuel filter, and tested the fuel injectors and they are fine. Also used a fuel system cleaner and sea foam on the car. The car only has 90,000 miles on it, Any ideas would be great thank you.

You need 4 things to start a engine. Fuel, spark, compression, and timing. If one is missing the car won't run.

Okay I'll look there and before all this happened my coolant hose some how got close to my belt and pretty much cut through the hose and was leaking. Could that have shorted the censor?

Thanks for the tip.
