Old Isuzu 2.8 injector pump problem

It would seem there are a few odd ways. It strange that it’s not had power to it since I’ve had it and it’s run fine until now. Thanks for the info. Saved me a lot of head scratching and money having the pump rebuilt for no reason.

Id check to see if it has a start solenoid. Some Isuzu 2.8 pumps do. It allows fuel pressure to build up for excess fuel start pressure, then once running it opens and allows fuel to return to tank. It's abit like blocking off the leak off. If this solenoid has no power once engine is started u can't rev up
Hey mate that was my issue, the oring had stripped on the start solenoid. Was allowing fuel to run straight back into tank. Been trying to find the correct oring as ive tried using round ones but no luck . Do you have a diagram or know correct size oring so i can order . It wasn't in the kit i purchased.

This engine is spare if any one needs bit from it now. Removing it from the old defender to replace with a Cummins. The issue I had in the end wasn't the pump but the timing of the pump. I rotated it and she ran perfectly. Stated it yeasteday after 6 months or being parked in the barn and she fired instantly. Probably the best fruck in the fleet, also the most uncomfortable. 😆

I have done the same as well, 2.8 was a great engine but I have pulled it out and have a Cummins siting in its place just needs everything connected up, have you started the conversion, collected all the parts?

I was lucky enough to buy an engine with all the bits. Decided to rebuild the engine, new piston rings, seals, plus injectors and a few tuning bits. Be about 200-220hp. Plenty for what I want.

What have you managed to gather together or are you still searching. I need a hx35w at some point to make it more drivable.
