im stumped, new to the site sorry if its hard to follow the post, got a 93 LT1 camaro, not much aftermarket done to the engine other than an slp intake and aluminum elbow, got it about 6 months ago, ran like a dream other than ses light due to bad coolant temp sensor in water pump, made it run rich, replaced it, couple weeks later opti went out, put a new opti, msd coil, and ICM on it, couple weeks later flexplate snapped and also ate starters nose cone, and on top of that the opti went out again, fixed all that, drove for a couple days, ignition switch shorted out causing QDM fault 1 and also no cooling fans, blower motor, or turn signals, fixed that drove three days ran perfect, sittin in a parkin lot after driving it all morning and it just shut off didnt sputter, fired right back up did it about four times and didnt do it anymore the rest of the day, next mornin didnt want to start finally did after about five minutes, drove it to town sittin there idling and it died again and wouldnt restart, towed it home, put another opti in and it fired right back up but was dieing like it was before didnt drive it next mornin went to start it and do some troubleshooting but wont start!!!! thinkin maybe the opti harness, but want some help and ideas, thanks in advance

Welcome to CamaroZ28.com! Always great to see another LT1 owner on the site.

You need to post "tech" questions on the correct technical forum. I'll copy your post to "LT1 Based Engine Tech".... lots of knowledgeable people there.
