92 lt1 isn't starting
I wrote a thread a few days ago about my 92 lt1 not starting. A few people thought it might be a fuel problem.
I just got the car towed back to my house and pulled out a spark plug that had fuel saturated on it, so I guess it isn't a fuel problem. Then I put the plug back in the plug wire and grounded it to the manifold while someone started the car and the plug hardly had any spark at all. I think its the opti spark but I was wondering if you all thought it might be something else. Could it be the coil? The car has 72,000 miles on it.
I just wanna be as sure as possible before I tear this thing apart and spend a lot of money on an opti and water pump. Thanks for any helpful input.

It could be the coil. I had a coil go out in my '92. There's also an ignition module next to the coil.
Usually failing optisparks cause the car to run poorly for a while. I'm not saying it's impossible, but I don't think optisparks go from 100% to dead in no time unless you really soak them.

Check your coil and ignition module first. Also check the pigtail connection to the opti. Also check the ECM. I had a loose connection at the ECM once that was causing me problems. Check all your ignition connections.
Is it throwing any codes?

Problem Solved!!!
I was able to trace the problem to the ignition module. Seems to run just fine now. Thanks for all your input in putting me in the right direction. This forum is good stuff.
