I have aquired a 1995 ZR 580 carburated CAT. The engine was swapped with a newer EFI motor but all carb and electrical parts,including stator, were put back onto the newer engine.The guy I purchased it from said after reassembly it started and ran fine next day, no spark!?! He blamed the CDI so I purchased a newCDI from Dennis Kirk still nothing. Took stator assembly into dealer and had coils tested all checked good. Took coil pack off wifes 2001 370Z and installed still no spark. Tested ign. switch and kill button with volt meter, checked good. There is also what appears to be a factory tether but it is broken and wires not hooked to anything I cant even find where they used to go. Any ideas would be greatly appreciated.
