Could be the crankshaft position sensor, maybe the camshaft position sensor

Might want to check out the fuel pressure anyway

There's probably one behind the harmonic balancer

Not sure about the other one, you might want to pick up a Haynes manual, they're very helpful

No spark... you've replaced ICM, coils, crank sensor, ignition switch

And you're 100% sure it's spark related?

Have you checked your fuel pressure?

Checked all your ground wires?

just got a phone call from the shop turns out somehow there was an electical short and somehow fried up some wires and sh*t causing the no spark issue so as of right now they are bein replaced and hopefully i will have my car back tonight its been awhile since i been on here but thanks for the input and feedback have to post pics of my car then the only pics i have are when it was white but its been a rough road this past year with the accident and rust attack but like i said cant bring myself to let go of this car so right now its in black primer with some silver trim just playin with options hopin to have it next year and painted and ready to go for the GM nationals in Carlisle,Pa since i live in York,Pa not that far away but i'll try to post more often to keep up to date.

not to try and sound smart or anything, but did u check the wire from the 7xcrank sensor( the one that connects to the driver side of the coil packs)...it is a twisted yellow/purple wire...that'll kepp it from starting, and is EASY to forget to re-install
