Im using an 18 circuit universal harness #10202, A TBI harness #60101 , and a 8 sw street panel #50410. This is all on a 1990 chevy 5.7. It starts right up but dies as soon as i let off the start button. I have no fault codes from the ECM. Im thinking it has something to do with the switch panel but cant figure out whats going on.

One problem I found on a '67 Camaro LS1 install is that the computer needs power in run and in start to run the fuel pump. If the computer power is from a start only power it will run in start but lose power in run. I had the opposite on the Camaro. Fuel punm would prime in run, but when started it would lose power to the computer and not start. When the key was turned back to run the pump would prime again sounding like it was running the whole time. Hope that helps a little bit. Good Luck.
Adam
