Ronhamann Report post Posted December 6, 2022 I have a 2004 Monaco Cayman with a 300 Cummins it cranks but will not run. There is no power to the engine lift pump, If I jump the lift pump the pump runs. Also no power to the engine fuel shutoff solenoid on the high pressure fuel pump. Does any one know how I can get a wire diagram for this vehicle. I have tested all of the fuses and relays that are labeled ignition. Share this post Link to post Share on other sites

Ronhamann Report post Posted December 10, 2022 Thanks for the information, I have a large fuse / relay panel in my left front compartment, and I testes all fuses & relays in this compartment labeled Ignition. I have several fuses & relays in my battery compartment, and I tested all fuses & relays in this compartment which is near the engine. I was not clear if the 2 blown fuses Cummins had located protecting the ECM were in a side compartment, or in line fuses mounted in the engine compartment.
