Bobcat 430 starts intermittently, all dash lights flash, and the fuel pump will not run: switch relay, fuel shutoff, or controller?
Short Answer
If a Bobcat 430 starts intermittently and then loses fuel-pump power while the dash lights flash, do not replace the fuel pump first. The stronger checks are the key-switch feed, start or run relays, safety interlock circuit, controller power supply, and the fuel-shutoff control path. A shared power or ground fault can make several good parts look bad at once.
What To Check
- Confirm whether the no-start happens hot, cold, after vibration, or only after the machine has run for a while, because that helps separate relay and power-feed faults from a bad pump.
- Check battery voltage, grounds, key-switch output, relay sockets, fuse holders, and whether the fuel-shutoff or fuel-pump relay loses command voltage when the dash starts flashing.
- Send the machine serial plate, relay numbers, controller connector photos, and the exact flash pattern before ordering electrical parts.
