I recently purchased a 05 Grand Prix paid $250 for it. Anyway, car will not start cranks good just no start. As soon as I got hit home I checked codes I'm getting p0463 and p0452. Ok. I found a fuel injector wire was pretty chewed up. But didn't find anything else . I checked spark on the first 3 plugs and I'm only getting spark on one. Now I haven't checked fuel pressure I will as soon as I get my hands on one. If anyone had any input I'm all ears thanks people!

Its best to use a simple summary for the title of your post instead of saying "need help".

Ok. Thanks. Still no help ha

Well, obviously, you have to check for spark off the top of each coil terminal, one at a time.......

Post back results.....since you have some spark, it'* not the crank sensor.....could be the ICM, or coil(*), or both....
