Okay I have a 1986 Ford Truck with a 6 Inline engine EFI which I plan in putting in my brothers bomb. The engine and tranny were rebuilt not to long ago and would run good. The problem is now that the engine will not start. I checked to see if it has spark and it does, I checked if the injector to see if it was shooting gas and it was. The last thing I did to start it was to give it gas manually thru the throttle body and it will start but it turns off again. Please help.
