Help in Clearwater FL
Hello all-------
I'm looking for a C4 electronics guru in the Tampa Bay area to help us with a project car located in Clearwater. It's a 1994 Coupe, in which we've replaced the original LT1 with a fairly high-tune 383 LT1. We have disassembled the dash, and are customizing the interior, and we now have some wiring issues to deal with. The computer has been tuned to the new 383, and VATS has been removed, but now we find the engine won't crank. We need help from somebody who is VERY familiar with the Corvette wiring harness who can help us troubleshoot the wiring and possibly computer...we just don't even know where to start. It may turn out to be E-Z or possibly challenging. Is there anybody who could refer us to a good person, or anybody who would like to take on an interesting challenge themselves? Thanks in advance,

The ECM serial communication goes through the dashboard so if the harness in or out of the dash has been modified/changed/damaged there might not be any communication with the ECM. When building my 90 race car I found when stripping out the unnecessary wire from the harness that 1) the color codes in the FSM didn't match the wiring under the dash 2) I had to cut each wire and then start the car to see if it would run before removing the wire. I wish you luck. Been there, done that.
