Default optisparked it up?

Opening up this can of worms for the masses. The 95 Lt1 is still not completing start up. checked plugs, wires, replaced coil and ICM. still no spark at the plug when cranked. only left with the idea that i need a new opti. with all the talk i hear about them going out. need some opinions on what to get. Here are the brands im looking at AC Delco, MSD, MSD cap and rotor? SUMMIT, JEGS, Accel. My car is mildly modifed with the usual to make it inhale and exhale. help is greatly needed,,,,,,,,,,,,,,

Get Delco, or MSD, out of that list.

You've checked all the fuses and made sure there is power going to the ICM, and spark coming out of the coil?

Many many people have had horrible results with the Accells, from working a few hundred miles to being DOA. I don't know how good Summit or JEGS' are, but personally from reading a lot of the stuff on here about the eBay china rebuilds being junk, I wouldn't risk it on such an expensive part. We know that true AC Delco remys are good, and MSD as well. There's that other company that makes the LTCC Opti as well, but they're apparently having a problems putting out their products and the tech support is lack luster at best.
