ltcc help needed from anyone here

ok i've posted a few times here looking for help on my setup but i'll try again...first off the basics....last year i had my 383 stroker built for me ..now mind you it was a torque build over a hp build....iwas having lots of problems with the optis self destructing on me in the terms of the fact i went through 4 in less then 1000 miles....later i blew my chain and took out some valves so i redid my top end with 195 comp afr lt4 heads and a custom cam from brett bauer "23x/24x" went with a cloydes dbl and had a tune from madz28.......nowing all the probs i was having with the optis i went with a ltcc unit ....now the problems...wiring the thing in correctly"as in the coil wires from the box going to the appropriate coil" the thing will not turn over or even crank right"for hose that have experienced blown up optis it crank fine for about 3 revolutions and then doggs for a couple and so on" if i switch banks on the coils"odds on even banks and vise versus" it will crank normal and even start some times....i had it running originally with it like this but it would gradually develop a miss and get worse......now i have it back to the switched setup again and i can get it running but i have to keep on he gas to keep it running and i'm throwing a 2 blink and a 4 blink in the unit...i'm running out of ideas here and i'm getting ready to put it back to a regular opti system again........if anyone has any ideas or if anyone has a 96 with a ltcc that can at least help me get the wiring right it would be greatly appreciated....also on a side note i hooked up a scope to watch the wave patterns on my low and high resolutions and with it wired in correctly it showed my opti to be all messed up....wired in with the banks swapped the waves evened out and were much better

Had a hard time deciphering your original post but I would just have to advise that you check your wiring with a fine tooth comb. Is everything ground VERY good? Sure you're getting your ECM signal from the right place?

Re: ltcc help needed from anyone here

Remind me what does the 2 blink & 4 blink mean?
Is your opti on right?
Are your coils new or used?
How are your grounds? You need to ground the hell out of that system.
