read this, (where are you?)

The fifth generation Isuzu Elf appeared in July 1993, with more sculpted headlights.
In May 1995 it received a minor change, including upgraded, cleaner diesel engines.
An OEM deal with Nissan led to the Elf also being sold badged as a Nissan Atlas and a Nissan Diesel Condor 20/30/35 beginning at this time, followed by the Nissan Atlas Max from 1996 until 2000. The Atlas Max was based on the new, lighter duty Elf 100 (June 1995) which was available with a 2-liter petrol or a 2.5 or 2.7-liter diesel engine.[20]
In May 2004, subsequent to a few minor changes, the Elf underwent a more major facelifts with new, larger, trapezoidal headlamps.
Another OEM deal was forged at this time and the Elf was now also marketed as a Mazda Titan in parallel.
In Malaysia, this truck is manufactured by Heavy Industries Corporation of Malaysia (Isuzu HICOM Malaysia) under the name of HICOM Perkasa, but carrying the Isuzu N-Series Commando badge.
? 100ft/lbs is a good guess, but is but a guess.

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.

this is no heavy truck forum. its only light and cars.
NPR what, (the number)
and what engine? fuel parts match up to and engine.
no year NPR. wow. and have gas or diesel engines.

Hi. If it has a rotary pump, the pump needs to be installed with the crank at 49 deg BTDC on the compression stroke cyl 1. Mark dot gear on pump with white paint. Line up dot gear on pump with line on pump bracket and install. Remove PRM sensor from bell housing and check if line on pump gear is still lined up with line on pump bracket.

Diesel !
cam ? timing? or the injector pump... ??????
ask Isuzu for a book.
wiki says, what is a space cab.>?? a 4,000 lb truck./van, sure.

The 4BE1 is a 3.6L direct injection engine. It replaced the 4BC2 in Isuzu NPR's from 1987- non turbo, VE rotary injection pump or Zexel/Diesel Kiki A-type injection pump. Bore and stroke are both 105mm. Power ratings in the last versions (NKR300)are 74 kW (100 SAE HP) at 3,500rpm and 242 Nm at 2000rpm.

Check sensors on the transmission. Best way to do it is a network diagnostics test. This will tell you exactly which sensor it is. It may just be a sensor with corrosion, try cleaning each sensor.

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
