Hello,
The AUX fuel pump is for adding fuel to the fuel tank. The PRIME fuel pump charges the engine fuel system. First check the CRANK switch, near the fuel filters, on the left side near the door hinge, make sure it’s in the NORMAL or RUN position. If this does not solve the problem then you need to check the fuel level switch or the primary fuel pump and that circuit.
