I know you can get a bad one, but this pump is new so is the strainer and the fuel pump relay. This model only carries 14.5 lb of pressure and it has that and goes up past 20 if you pinch the return line pumps do not run on these early models. When you first turn on the ignition it must see oil pressure or ignition impulse before it runs I have tried to find out if there was a kit to make it like the later models that would run for eight or ten seconds when you turn on key. My local Dodge Dealer told me they did not have anybody that would know about one that old and could not look up a recall or modification from that far back. I have a 1998 model with a 5.9 and the pump runs as soon as you turn on the key and it starts instantly every time hot or cold. I have checked the power to the pump relay and it is hot at all times and the pilot is hot with the key on and energizes with ground from somewhere that is not there, until it sees a signal from somewhere else if I jump the relay the pump runs and it starts instantly, but this could be a fire hazard in the right situation.
