I built a wiring harness for a guy to put an LS2 6.0 E40 and T42 tcm in a classic Pontiac. for whatever reason he cant get the injectors to fire from the computer? He has 10 volts at the pink wire of the injector, I have already talked to him about making sure the injectors are all pined right and in the right spot, they are. Still will not start. They can jump the injectors with a power probe and the injectors will open and spray fuel. He has 58 psi on the rail. It will run if he sprays starting fluid in the throttle body. Sent me back the computer I tested the injector circuit with a node light, the computer is sending the signal. He hooked a TACH up to that wire and he is getting a signal, which tells me the crank sensor is working. Is there anything anybody can think of that would not let the injectors fire?
Thank you for any input.
