1986 chevy s10 2.5l no gas coming from injector.
I have no gas coming from my injector it a 1986 chevy s10 2.5l I have replaced the fuel pump,oil pressure switch & I checked and oil would come out the hole when turning over,fuel pump relay,cleaned tank and lines, I baught a pressure regulater kit from orilleys and built it,fuel injector,fuel filter, throttle position sensor, mass air sensor, I have traced all the wires back to the computer and they all have good continuity and all look good,i have checked the fuses and they all look good, I have also replaced the computer but it didnt work after that so I took the computer back, I am throwing no codes and if I pour gas down the throttle body it starts right up but doest stay started. I have spark . I am getting 11.7 volts through the red wire and the blue puts some out when turning it over. when I put 12 volts to one side of the injector and ground the other out it spits fuel... I had a pressure tester to it and it would go to 10 or so pressure after I turned it over for a few seconds.. none of this has worked and It dosnt have a single fuel inj fuse or fuel inf relay..
