1995 Truck, no mods, 270k miles
I ran out of fuel on the way to work (fuel quantity sensor in tank is bad again and my fuel-o-dometer method failed me). Now I have done this once before and was able to get it reprimed on the side of the road. This time I am having a VERY hard time getting it primed.
While on the side of the road I was able to get the truck to hit and run for approximately 60 seconds then it lost prime again. Giving up, I had the truck towed home now working on it here.
I put 9-10 gallons of fuel in the tank - that should be sufficient no?
I have pumped the priming pump a lot. As much as 6 minutes straight averaging 2 pumps per second. I have the first three injector lines cracked on the injection pump as well. I had replaced the o-ring about a year ago but seem to have choosen an o-ring too large and it was binding on the shaft of the priming pump. So today I put in a smaller o-ring. After cranking the engine over for around 10-20 seconds the priming pump squirts out fuel when I go to pump it again.
Where are the check valves on the system that keep the system primed? Could these valves have gone bad? Note: truck was running great before I run it dry.
I am at a lost as to what is wrong now. My secondary vehicle is also having problems as well (SAME day - really bad vehicle luck) that I can't readily diagnose, so I must get my truck running!
Help!
