I have a 90 Daytona VNT car I'm trying to tune, but none of the T-SBEC cals seem to run it. Tried the A415 Daytona VNT code, and tried the A577 code (non-vnt). Neither primes the pump or runs the car. I would think bad computer, except that it had a FWD-P chip originally that will run the engine just fine. Thought maybe I had a bad chip, but I tried 3 different chips also.

Anybody else ever run into this, or something similar?
