WE HAVE LIFT OFF!!!

I got it to start!!! Finally after 2 weeks of headaches.

It turns out that it was just my coil module, as I was getting spark but it wasn't strong enough to start the motor. Is that screwed or what...

Thanks for all your help and suggestions guys!!!

Glad to see you have found your problem zapper. I on the other hand am no closer. I tried watching the pressure(actually I cranked while my gf watched) from the numbers she was spouting it held pretty steady while cranking. I think the lowest was 35psi. I am just grasping at anything I can try now. I really need a fresh perspective to look at it with me, unfortunitly there are not that many knowledgable Lt1 owners around here.

well it seems that you have determined that the fuel pump is not the problem as 35 psi is more than enough to start the car. Did you check to see if you have a very strong spark? I've replaced my opti, my pcm, plugs & wires, and my coil. So I've changed all the most common things to go.

All you need for your car to start is fuel which you have, spark (a strong one apperently), compression, and proper timing. If you have all these things there is no reason why the car doesn't start. Besides the obvious things like an alarm with ignition kill or no battery power or no gas.

Good luck with it as I know how you feel...
