Hi Guys! I got this van a while ago for my business to help move heavy items around. I think it's an ex-u-haul van.
It's got that international 7.3L diesel in it. I am ok with gas mechanics, but I don't know a whole lot about diesels.
Long story short. I used it a lot, and it ran perfect. Then I parked it for eight months. I went to start it today, and all it does it turn over, endlessly, it doesnt sound like it even wants to start. Just a consistent turn over.
I love my baby, but I don't even know where to begin to try and fix her. To make matters worse, I'm a bit short on funds to hire someone to come fix it for me.
The ol IDI (indirect injected) diesels had some return hose, injector cap o-ring issues with age/mileage, as well as injection pump failures. I’d also be suspect of the fuel lift pump (supplies fuel to the filter canister) or, the injection pump itself. What you might try first is after some cranking, at the fuel filter there’s a Bleeder valve, looks like a tire valve. Depress the valve core for a release and see it it purges a small amount of fuel, air, or nothing.. If fuel is expelled at the filter,, then break loose/ loosen one of the forward (or any) fuel injector line nuts. Have a helper crank the engine..
Does the line pulse a small amount of fuel from the loosened connection?
You can also put a clear fuel line on the fuel filter bulk head connector to injection pump, and the return and look for air bubbles being moved through the system during cranking. If air is present, then isolate the cause..
