Fuel pumps are electrical devices.
You can find a wiring diagram for your 1997 Isuzu Trooper in mechanical service manuals. The mechanical service manuals can be found at most local libraries.

Automatic is a gm 4l-30e unit.
I would say it is an electric fuel pump inside the gas tank
If a 1994 Trooper loses power going up hill and has a spark knock in the engine, the compression of the engine should be checked. It is possible that the vehicle is not running on all of its cylinders.
If you need a cylinder replaced, let a qualified gun smith do it. If it needs to be timed, you won't regret spending the money.
It is the Achilles heel of the pwr train system imho

Disconnect battery, remove electric wires from starter, remove mounting bolts, install new part in reverse sequence.
AGE ! if it is low compression and not no compression then your piston rings and valves are worn too much and the engine probably needs to be rebuilt.
