Question about 1988 Dodge Ramcharger
1987 Dodge Ramcharger, one book states inline electric fuel pump, another says in tank.
I cannot find fuses?
If I poor gas directly down the throttle body it runs, it is not getting fuel.
Where do I start?
If you think it's the pump ... Find your owners manual to find locations of fuses and relays ... First is this vehicle on level ground? Does it have sufficient fuel level (1/8 tank or more) then have an assistant turn on ignition switch to run position (not start) while you listen under the tank to hear a pump ... it may only make a noise for a few seconds ... is there fuel getting to the throttle body at the input line (it could be the injector) if there is fuel pressure at the throttle body/injector it may be the injector itself) >>>If no sound is heard ... first check for power at following locations >>> Fuses >>> Fuel pump relay >>> harnesses/connectors going to the tank from the front all the way back >>> connector at pump (tank likely will have to be emptied and removed, and you would rather avoid this if possible) >>>pump ... I don't suspect filter, as I've never had one suddenly fail completely

Then, disconnect the fuel line at the throttle body (unless there is a fuel pressure testing port) and see if there is fuel when you turn on the key.
If not, fuel pump, probably in tank. (assuming there isn't one on the side of the engine..)
If there IS fuel in the line, then the computer may not be engaging the injectors. Check for wiring issues on something that old. Maybe the main junction splice for power to the computer. (Not sure where on that one, sometimes it's in a dumb place, like near the battery and it gets corroded).

I had the same problem with my old 1987 Chevy blazer s10. The problem was the ground wire of the fuel tank was rusty and it broke. So simple was the problem. But before that, I checked and change the fuses, the fuel filter, the oil pressure switch (this is related to the fuel pump to) and finely when a was ganging the fuel pump saw that the ground wire was broken or damage.
I hope this can help you.
