I swaped the entire drivetrain from my 92 RS into my 87 camaro that came with a LG4 originally. I used the engine harness and computer from the 92 and the dash harness from the 87. I have spark, and fuel is flowing, but it is going straight through the throttle body and back to the tank. My injectors aren't firing at all. So I think my problem my have to do with the fact that my RS had that VATS system? What can I do to fix that problem, or do yu think it could be something else? I can't remove the dash harness, VATS module or column from the RS, I need that for my other setup.

 

you need a chip with the VATS disabled.
I can burn you one if you want.
email me for the details.

Aside from needing a chip without the VATS, I have a problem that needs to be fixed first. Since I am using my 92 TBI wiring with the 87 dash harness that was used in a carbed car I don't have the fuses for my injectors. So even without VATS they still won't fire. If someone could tell me how the injector circuit works, or what I need to do to make them work with my 87 harness?

Thanks

 

If you had TPI, I could tell you exactly how to wire up the injector fuses.

go to www.thirdgen.org, I guarantee someone there will know or have the wiring diagrams to help you out.
