DURAMAX TIM is off the scale
Default

U should also have an oil pressure cut off so if oil pressure drops the fuel pump stops.
I had one on a GM diesel that had to be replaced atleast once a year.

Klaus, does we have the oil pressure/ fuel pump sensor on the H2?
Some vehicles have an impact switch that stops pump.
As a safety concern it should have some way to shut off fuel in event of a wreck and the engine stops and the key is still in the run position.
I don't know how involved u want to get but u could check for continuity (sp?) at the fuel pump or have Klaus get the relay terminal #s to check from above.
