Fuel pump or wiring issue?

[Jim.Zombii_9]

Trying to help my dad with his 2020 Kubota Z421 after it got jumped backwards. It'll crank but refuses to start and keeps popping the 15 amp fuse near the seat. We can't hear the fuel pump either and I ordered a shutoff solenoid but don't see 1 anywhere on the mower. Could the jumping have damaged a hidden relay or something in the wiring harness? Wondering if anyone's run into this on the Z400 series.

Definintely jumping it backwards can definitely fry a relay or blow more than just the visible fuses lol, that 15A fuse blowing near the seat usually ties to the fuel system. You should check the key switch relay and any inline fuses hidden under the seat or near the frame rail.

Thanks, this gives me a better direction. Is the key switch relay easy to spot on the Z421 or buried in the harness? I'll try to trace the wiring near the frame rail tomorrow and see what else might be hiding.
