onan 7.5 dkd diesel won't start

[mikemabe]

Its been running fine. Ijust replaced the fuel solenoid and now i have no power to any of my start buttons to start the gen. The solenoid kicks on and the pump runs and then it trips a breaker beside the on button in front by the gen. It doesnt crank over at any location start buttons. I can jump it with a screw driver at the starter solenoid and it run fine. Please help

Since you just replaced the pump and it now causes a fuse to open, take a close look at the connections you made. After 40+ years of electrical service work it has been my experience if a problem develops right after I replace a part, the cause is usually something that I did.
