try dealer

this is no NPR forum.
not even close, just cars and light trucks 4k or less.
not 27,000 lb ones.
hope you get lucky,
I buy the book, so can do work and not beg for 1000 pages 1 by one.

go to isuzu,
walk in
and buy the book on your big truck.
I do not think there is any online big truck support books.
nor in Autozoned.
sorry....
or get it serviced?

btw, no engine stated.

most likely a light relay full of water

Sorry we do not have wiring diagrams for this car

youd need the NPR heavy truck, FSM book page on radio wiring
buy book at any Isuzu heavy truck dealer.
we dont now what radio option cam on that NPR
nor what country , other countries use different radios.
so..... this is USA forum, and we dont have NPR books.

a pickup truck right, in Africa>?????
this is usa forum.
and we dont have Kb250s here, no KB period.,
and , no books on it. for that reason. no online books either.
nor alldata.com coverage, same reason.
why not go to YOUR Isuzu dealers ( ours is like" Elvis , has left the building" (country on cars) we have huge NPR Isuzu trucks though.
and get the book on that car, called the FSM.

Has to be a fuse gone or wires broken

ok I had same problem with my 1996 Isuzu npr 5.7 gas burner. on top of fuel tank are wires and cant remember if it was 3 or 4 but anyways one of those wires is your ground wire to the fuel pump its self. make sure the wire has a good ground on the frame and/or the bed body of the truck. wish you the best hope I could help you
