2000 Corvette LS1 in 66 GTO

**51chevy** · 10-07-2011, 01:44 PM

Currently putting an LS1 in a 66 GTO for a guy. Have installed an ECM and wiring harness reworked by Fuel Injection Connection into car. This equipment was provided by the owner but I did not get wiring diagrams or instructions. Have call FIC for help but no calls returned. At present have power at each coil and each fuel injector but no fire out of coils or fuel out of injectors.

Any suggestions on where to start to trace out the problem?

Thanks

Yikes. Without schematics that is going to be one difficult job. Any idea what the ECM is out of originally, or is it a complete aftermarket engine controller? Nothing like seeing a company stand behind and support their product.

I took a look at their website and do not see any information on engine controllers or wiring. Looks like they only specialize in injectors.

well if its a 2000 Corvette ECM/wiring then each coil and injector are fired by a signal from the ECM. Most likely there is something wrong with the crankshaft position sensor or its wiring/connector. That would knock out both ignition and fuel injector drive.

Info was in the title -- I read the post.

The ECM and harness are supposedly out of a 2000 Corvette and FIC did a revamp on the wiring so it could be used in earlier vehicles. The T56 trans is supposedly out of a Camaro of about the same year. You are correct, with no instructions and only the OEM schematic, which the color-coding on the injectors does not match, it is a bit difficult to trace the problem.
