I have a 2000 Dodge Ram diesel that quit running abruptly after hitting a very bad bump. Is there a rollover fuel pump/ engine shutoff switch on this truck like cars have? If so, where is the reset for it? I don't want to change the injection pump and find out I have a minor electrical problem. We have checked everything else, but can't find any reference to a rollover shut off like most cars have. Thanks for your assistance.

No rollover switch. Do you have fuel pressure? Have checked ASD relay and pump relay?

Thanks for the quick response!

I have fuel pressure and plenty of fuel coming up to the injector pump, no pressure after the pump, tried to bleed system, no fuel at injector lines.

I have checked the fuel pump relay and the ASD relay and they both are working properly.

I bled the low pressure side thru the banjo fitting while cranking the engine. Got some air out. Afterwards, still no fuel at the injectors.

Hi, there isn't one. With engine cranking, I'd check voltage and ground at fuel pump connector. Dark green wire with black tracer is voltage, black is ground. Next,I'd check circuits at the fuel pump relay.

The picture is the fuel pump module, not the relay.
