Can you describe what happens when you try to start the car? For example, does it turn over, sputter, etc.

it just cranks and cranks and cranks some more...every once in awhile when i release the key is may sputter but only once in awhile...no weird sounds or nething. the only things i havent replaced yet are the cap and ignition switch. but i heard i wouldnt have spark if either of them r going bad. should be gettin them in the next couple of days. i love this car and dont want to get rid of it. to much work ive put into it. shes fast when it starts. lol thanks again every1

Have you pulled an injector to see if it is actually injecting. If not pull one of the injectors, put it into a jar and see if it injects.

A: Check your F'ing grounds.

That's not it, but do it anyways.

B: Replace your coil. You can get a weak spark and the car won't start.

Before anyone want's to say "No way it can't be the coil" Been there done that. I froze my *** off on the Canadian Border and Chris walked something ike 800 miles back and forth listening to advice like "It can't be the coil" business.

If you see the injectors spraying fuel, then I'd look a lot harder at the ignition side. If you are getting spark then my guess is that it's a weak one. I would expect that a healthy spark with erroneous timing would at least produce backfires. Have you checked the cam belt to see if things are lined up properly?
