Fuel pump checking procedure

Good morning everyone!

As the last thread was getting long and today is the day because I’m traveling again to try to pickup my 96’ Bounder I need to ask you what is the complete procedure to check if a fuel pump is dead or alive.

What I already tried was:

- disconnected the fuel line before it reaches the fuel filter.
- swapped the horn relay with the fuel pump relay while turning the keys to ON position.
- jumped the fuel pump relay while turning they keys to ON position.

In any of these steps I got vital signs of the fuel pump so not sure if I should check something else before get to the hard mission of drop the leveling jacks and fuel tank.

As the rv was parked for 10 years I’m suspecting that rodents could chewed wires somewhere. Do I have a way to connect a battery directly to the fuel pump?

Thanks again!

Did you check for power at fuel pump relay ? If you had power at relay... then you said you jumped it.. that would give you direct battery current to fp.. so make sure you got power at relay.. next as last check.. check for volts at relay.. jump relay.. go back to tank and use test light with sharp probe and see if one of the fp wires has power.. good luck and keep us posted

Is there a wiring harness connector back near the fuel tank? Don't start poking holes in wires until you find out. There are voltage testers available which will test wiring without probing into wires.

Relays aren't complicated. 87, 87a and C are the load side. C should be hot, 87 or 87a to the pump. 85 and 86 are the coil engagement wires. At least on the common ones. So connecting C to 87 or to 87a whichever is used should turn on the pump
