Hey everybody, I want to pick some brains on what is causing a problem for a friends Jeep. First off it is a 1993 Jeep Grand Cherokee with the 5.2L. What seems to be happening is his injectors are not firing. The vehicle has spark and I can keep it running by dribbling gas down the throttle body. I have checked for fuel pressure and I have 42 lbs at the rail. Does anyone have an idea of where I could start looking or what would kick the injectors to work. I am thinking of renting a node tester and just seeing if the injectors have pulse or not. Thanks for the help in advance.
