Question about 2004 Pontiac Grand Am
I have been scratching my head on this issue for sometime now.
In the morning hours the car will crank over fine, you can hear the fuel pump prime, no security light but just will not start. I have to leave to work so I have no time to trouble shoot the issue. I come home in the afternoon and it fires right up and runs fantastic. I have already ruled out the security issue, I have changed both the crank position sensors, the battery is new, starter works good. The car has less then 90K on it. Our mornings here have been in the 70's and high 90's in the afternoon. I'm thinking now it's a thermal issue with the computer.
Any other ideas that I might check?
Check the MAP sensor and the wire harness to the map sensor. Next time it will not start, try disconnecting the MAP sensor and see if it starts. IF it does then change the sensor. Good luck and hope this helps.
