8.6 Checking Fuel Pump

See Graphic: wc_gr003437

The fuel pump (a) is mounted inside the frame on the left hand side.

By checking the operation of the fuel pump one can determine quickly

if the problem is associated with the machine’s circuitry or with the

engine itself. When the key switch is in the ON position, power should

flow to the fuel pump. When the fuel pump receives electric power, you

can hear and feel it run. If the fuel pump does not make any noise when

the key switch is in the ON position, it is not receiving power. The

problem is within the circuitry of the machine. Start troubleshooting by

checking the wiring to the fuel pump; continue with checking the 15A

fuse. If the fuel pump is receiving power and pumping fuel to the

engine, the problem is within the engine. See the engine

manufacturer’s repair manual. If the fuel pump is receiving power but

not pumping, the fuel pump has failed; replace it.
