Thread: Fuel Starvation problems

Hi mate,
most likely an air leak in the fuel line. I have experienced similar symptoms with my truck and initially presumed the fuel lift pump to be the culprit. When I then replaced it and the problem persisted I started investigating, following the fuel lines from fuel tank to engine. The fuel sedimenter was full of crap, as yours. The giveaway was a rusty stain on the plastic collar inside. On more accurate inspection a tiny hole on the lock of the sedimenter could be seen. After replacing the unit the problem was gone. There is a thread about this somewhere on the forum, with pics. Try a search.
Good luck!
Cheers

could be

clogged pick up
blocked or leaking sedimentor
blocked or leaking line
blocked or fuel filter
internally leaking lift pump
internal failure of the intitial pressure pump inside the injector pump (highly unlikely)

As Blknight said. I traced mine to a clogged intake in the tank. And there was a "ball" of diesel algae floating in there that was blocking things, starve, stop, algae float away, all good for maybe a few hundred Ks then back again! Drove me slightly more bonkers than I already am for a while
Cheers Scott

Hi everyone, just an update to say that I'm hopeful that I have found the problem with the fuel starvation. After trying to inspect the fuel lines and checking the connections I discovered that one leg of the fuel lift pump it actually spins where as the other is fixed in place. So I'm thinking this is where air is entering the fuel system.
Have ordered a new lift pump for replacement so now it's just a waiting game for when it arrives... Thanks for everyones input, much appreciated

Hi Rob,
thanks for the update! Whilst waiting for your replacement to arrive, you can bypass the lift pump and see if the trouble disappears. Your engine will run even without the lift pump, only on steep inclines and such it might experience some problems. If the symptoms persist, continue searching.
Cheers

Might be an idea to check the wire connection to the fuel cut-off solenoid on the Inj. Pump, cold be loose, would cause fuel starvation, Regards Frank.
