Did you pull a plug to confirm there is no spark?

[GrandPrixgtp2000]

Yeah, thats why i went home and got my MSDs and it still dident work, it should be getting fuel though because I could hear the pump turn on when I turned the key on.

Hard to pinpoint an issue like that. I don't know if a MAP sensor would cause no spark or not. If it's all the cyl not getting fire then yes, ICM would be my first guess, could also be a crank or cam pos sensor. I had a crank pos sensor go out and I had no spark (on a 3100). Could be as simple as a ground also. Let us know what it turned out to be.

[GrandPrixgtp2000]

I will let ya know. I was thinking Crank pos sensor but wouldent it have a code?

[rperry435]

Map sensor will not cause a no spark scenario.

Crank sensor can be bad without setting a DTC.
