I was running my excavator today for a couple of hours when it shut down with no warning. It did not even sputter.
Here is what I know so far: Engine is Isuzu BB-4BG1T
Half tank fuel, new fuel filter 10 running hours ago.
Using the primer pump we have fuel squirting out of the lines before injection pump.
The main filter and the water separater were full when it shut down.
When we crack an injector and turn engine over there is no fuel at injector
Same fitting that squirts fuel with the primer pump does not squirt when we turn over the engine.
Seems that the lift pump is not working to get fuel to the injection pump.
Is this a mechanical breakdown of the lift pump (broken)?
Or is there a electronic problem possible.
I was tracking when the motor shut down with no warning and now has zero fuel to the injectors.
Any help is much appreciated as I was supposed to move it to a post pounding job on a vineyard tomorrow.
Thanks, Tim
