Pump working? (Hard wire the pump to the ign, be sure to have a return line)Holley varies the ground to control the pump...SUCKS.
Use a toothbrush with some carb cleaner and clean the head of the injectors. The injectors can be removed and cleaned....Basically the same thing as a Chev tbi, as far as the throttle body goes, just a little more CFM.
Check your filter!! The injectors HATE crap. About anything will clog them!! I run 2 filters. One at the tank, one at the tb.
Check powers and GROUNDS. Reduntently ground everthing!!!!!!!!!!!!!! Sounds stupid, but a Body ground is not good enough! I ground motor to frame to body to battery to motor, then run a ground from the loop to the computer. Seems rediculous, but it works. Make sure you have a clean, good, constant power supply to the system too.
Most the probs I have seen with Projection are related to ground, power, and pump in that order!
I have been running one of the same old style systems for a couple years without problems. I got mine cheap too, from a friend that could not make it run.....
