Default LT1 help

was wondering if any of you guys might be able to help me pin point my problem

ok i swapped what i found out is a 94 LT1 (thought it was a 95)into my 84 corvette. got all the wiring hooked up, gettin 5 volt references at all the places im supposed to be gettin it but all it doesnt is crank but no start. im not getting any spark.VATS has been deleted



could it be:

bad opti
opti module
igniton control module
electronic spark control module

??????????


i just want to knwo what i have to buy to get it running. wish i had the money to do the whole swap to get away from opti but maybe some other day.

this is all it does

1st make sure you have all your wiring correct.

Double check all your connection, and connection points.

By the way, that's an excellent choice of color you made on your 93.
