I have a 1991 Ford Bronco I put new fuel pump, pressure regalater and I have to put gas in the throttle to make it crank after it cranks it run good until it sits an hour or two.
Bad injectors or a bad fuel rail have both tested for psi while it is running and after it has sat for the hr or so it should not loose psi to the point were u need to prime it in order to start, what size engine do u have is it the 4.9 the 5.0 or the 5.8
