Default Good guessers come in??

Let me go over the storyline of the car. September 30th was the last day the car ran. It ran great all night with WOT runs on the highway then 2 mins before I got home it sputtered and wouldnt start. It has been sitting in my barn ever since then and I havent worried about it. Once again the car has brand new MSD opti, whole Racetronix fuel pump setup, new tr55's, new 8.5 mm wires, new duralast battery, and the MSD coil has been replaced a couple times but I dont think that would be it becuz the car would still start..What could keep it from starting??

Have you actually checked to see if you are getting spark and fuel?

So, does that mean that it tried to start? That is, it hit a few times.

ive replaced everything and having the same problem. It could be a shitload of things. Best thing to do is get a test light or something better and look for a write-up on how to diagnose the problem with a test light. Thats what I did and it led to the ICM and Ignition Coil but now the car will run like a bat out of hell for about 10 miles before it shuts off and won't start back up until it cools down.

I'd guess that you are not getting fuel at the rails. Just a hunch.

Ever check the Ignition Control Module? Like everyone said, start with the essentials. Throw a fuel pressure gauge on the test port and see if you're getting fuel pressure. Check for spark
