wierd ass problem with cutlass

[SappySE107]

ben and i finally got it to start. the injectors wouldnt pulse unless i UNPLUGGED the tps and coolant sensor. then it sucks up a gallon of fuel after about 15 minutes of running like ass and shooting white smoke out. plug thenm back in and nothing. has anyone seen anything like this before?

I am working on a way to control injectors with engine KPS pulses, variable Duty Cycle, delay, and frequency.

The car is beyond internet help, that much I could have told him. Its down to wiring, which is a junkyard wiring harness that we had to cut in some spots. God knows whats shorted out, whats not grounded, etc.

sounds like my car at the last meet. Damn 5 volt referance wire.

we probably cut a ground wire too short and it went into the loom. it's the only logical conclusion now...unless the harnesses between a 90 lumina and a 91 grand prix are different.
