Troubleshoot a miss I have LS2 with FAST harness in 67 Corvette convertible. I have a miss in number 2 and 6. Chevrolet tech ran codes and indicated the ECM was bad.
After waiting 6 weeks on backorder from Chevrolet, I installed the new ECM and same problem
Pull plug wires and they are getting no fire.
Switched coil packs and they are all good. At this point, is it fair to assume that harness is bad or can other diagnostics/fixes be performed?
