the threads looking for a solution to my llift pump problem. I've fitted 3 in the last 3 weeks all delphi.
I was towing about 1.5 tonne when the engine gradually died then wouldn't start. Dragged it to my mates where we checked through eventually realising the lift pump wouldn't prime. Took that off, new one on and away it went strong as ever, for a whole week... It died again, we couldn't believe it was the lift pump so we checked everything before we came back to the pump and lo and behold it wasn't pumping. We took it off and pumped the arm and it seemed to be sucking air but when we put a pipe on it and fed it into a jar of diesel it wouldn't pump the diesel.
So we put a new pump on and away it went again, for 5 days, same symptoms. This time I emptied and cleaned the tank, a new stack pipe, the sedimentors been removed, another new filter and new lift pump. That was 3 days ago and it's going again,there doesn't seem to be any air getting in but the next step is to replace all the pipes.
I can't think of what's causing it, the weird thing is I tested one of the pumps we took off after a week or so and it was pumping diesel again.
Any ideas chaps.
