pump is not running. I have a circuit that is drawing current but hear no sound from the pump. can fire off on starting fluid. Does this van chassis have a pump module like the F150 trucks?
It is a long camper with a 55 gallon tank.

 

Not knowing exactly how your vehicle is set up,
the first thing I would want to know is what is pulling that power? You might be able to isolate that by removing fuses and see which fuse allows the drain to stop.
Depending on what you find you might want to confirm inertia switch function. I believe that switch is located on the upper part of the passenger side kick panel.
