Wont start, . Ok, here w e ggoooo
checked fuel lines, pumps good, seems its getting gas TO the fuel injectors, and thats it, we capped off the return gas line, have checked relays, fuses, and replaced the ICM, turns over, will run if you dump gas in throttle body, but only till its gone, the injectors have been replaced, I am so frustrated, dont know what to do, need it running, have looked at everything according to haynes manual, fuels runnin about 18-25 ish psi, what am I missing?
