Lost fuel pressure
I have a 1987 2.9 V6. Two days ago I changed the fuel filter. After restarting the truck it ran great for about ten minutes and then shut off. It acted as if there was no fuel. I chalked this up to the possibility of air in the line. Is there a bleeding process that I was unaware of? I was towed toward home when I dropped it into first and dumped the clutch and it was off and running. Today, started up just fine, drove for almost 50 miles and parked. Came back a few hours later and it started right up then died within a few minutes. I checked the schrader valve on the injection rail and there was little to no fuel pressure. Had to use a few squirts of starting fluid before it finally fired and drove home without issue. I don't know if I need to replace fuel pump or what. Any help would be greatly appreciated.
