My brother is out of state with my truck and it broke down. Here is what we know so far. He pulled into a truck stop and the truck started a high idle and then quite. That usually happens when it runs out of fuel. There is fuel getting to the IP. It looks like the shut off and metering solanoid are working. They are clicking anyway. Could the shut off solanoid still be the problem. It seems to me like it is. The reason I say that is my glow plugs quite working rescently and I have needed to start with either. A few mornings either was not doing anything and then all of the sudden pop and it starts right up. Like the fuel supply suddenly opened. Now either does nothing to try to start it. Should either do something to it even without fuel. Someone told me that without any fuel supply either might not even fire it. Does that sound right for a 6.9? So basically the problem has got to be the fuel shut off or timing. Is there a way for the fuel shut off to be by passed to get him home? It is 4 speed so the engine could be killed to shut it off when needed. If the problem is in the timing what could have happened so suddenly, no abnormal engine noise was heard. The engine is suppose to be a factory replacement with only about 25K miles. Need help asap if someone has any ideas.

 

you say you have fuel to the injection pump, but how much. lift pump coulda went. might be supplying a little fuel, but not enough to fire it.

 

Loosen a fuel line at an injector and make sure you are getting fuel thru the pump, the lift pump only get fuel to the inj pump, the inj pump then creates the pressure to the injectors.

 

Thank you, we do know that fuel is getting to the IP. The IP is not creating any pressure to the injectors.

I guess it still could be the lift pump not getting enough pressure to the IP. Have you guys ever heard of the IP losing its timing for any reason. Is it prone any internal gears breaking or anything?

 

not prone to it, but i havwe seen pics of the shaft broken off inside the pump.

 

I am going to pick him up today with another truck. Hopefully we can get it home and see what happened. I still think it is something electronic but without being there it is tough to say. The lift pump is also a strong possibility if it is not creating enough prime pressure. Will know more in a few days.
