95 dodge 12v current mileage 286K
injection pump rebuild 20k miles ago.
reman injectors from Oregon fuel injection 56K ago
highway speeds runs fine starts missing out of the blue I let off throttle engine dies coast to side of road restart runs fine. Happened about a month ago then week ago then a few days later then it continued, limped home was able to run the engine with the miss only if I restarted immediately after it missed and died. If I waited 30 seconds it would run fine and I would have to runs rpms up for a minute or so to duplicate problem again. The next day I ran it at 1500rpm for 4 min ran fine. I drive 28 miles one way to work, the problem only happened on my way home.
Fuel pressure 22psi idle 1500 -2000 rpm build to 24-25 psi. observed exhaust while I duplicated problem at idle there was absolutely no smoke out of exhaust while missing and no drop in fuel pressure. I have hooked up some clear tubing inline with the return and feed line from the tank. I have bypassed the inlet heater and there is a new fuel filter installed I also have a Vulcan draw straw installed 50K ago. I have bypassed the fuel heater, pulled the tank out and ran the truck with the return going into a different container to verify there is no air getting in. I had a similar symptom before the injection pump was rebuilt but a harsher miss and the throttle shaft seemed to be hanging up. Has anyone had this symptom before? Is there anything in the injection pump that can cause this symptom intermittently?
