I just cant win.
Check for spark directly at the coil first. Get an old spark plug & spark plug wire and plug in to the coil laying the plug on the intake or something grounded metal. Crank & watch. No spark? Check fuse, 10 amps in the under hood fuse block.
Good spark? The problem is inside the distributor.

Thats what im going to do when i get home later this week. Im out of town for work right now and its bugging the crap out of me not knowing where whats wrong. Thanks all you guys for all your help.
Welp i just got back a few hours ago and started trying to figure out whats going on. I cleaned the corrosion off the opti harness, checked for spark at the coil, checked EVERY connector i could find and got no where.

Mine was as gm had made it, if I wiggled it to the right spot, it would fire right up and run just fine, got a new one from napa, soldered it in and it hasn't given me a problem yet. It has also happened to me on the icm and now the coolant temp sensor in the wp. When I go 24x, that efi connections harness is looking pretty good to me after these problems, although I may try the repin kit to save $.

Verdad Gallardo I remember from a previous thread on here a guys ignition switch caused a no spark condition like you have. Ill see if I can find the thread.
Well, from my understanding the optical sensor in the Opti sends a signal to the pcm. The PCM then sends the signal to the injectors and ICM/coil. If your injectors are firing then that would rule out a bad opti or PCM. Then you could start checking the wiring harness. A bad opti can cause a no spark condition at the coil and the injectors wont puls IIRC. I doubt its the opti but it doesnt hurt to check.

Thanks man i appreciate the info i didn't know that it would keep the injectors from firing. Ill get on checking it first thing when i wake up.
