you have the pump, so you might as well start with that..(is this the original pump from 2000?)
If it's cranking strong, I would think that would rule out the battery and relate cables...
If you're certain the problem only occurs when below a 1/4 tank, then I don't see how its now fuel pressure related.. So start with the pump, and go from there, especially if you're experienced a stall while its running as well.. Fuel filter old?
If you're not certain about the 1/4 tank symptom .. then also check for loose grounds involving the fuel circuits as well, and test the fuel relay, or swap one in if you can find one cheap.... Posts in this Thread:
