TROUBLE CODE 33

4.23

GENERAL

Fuel Pump

The fuel pump assembly is shown in

Figure 4-163.

ECM Pin

3 provides ground to the fuel pump. Code 33 will set if:

●

BN/Y wire is shorted to 12 volts. This will also cause the
ignition fuse to blow. See

Figure 4-164.

●

BN/Y wire is shorted to ground. This will cause the fuel
pump to run continuously even when the motor is not
running.

●

Fuel pump motor stalls or spins without providing fuel
pressure.
