Check the fuel pump relay and fuses it may not be getting power when you turn the key on.

Where is the fuel cutoff switch on a 2000 isuzu trooper


which engine, ill toss coin, land on v6
check fuses first.
wont crank? that grrrrr grrrrr grrrrr sound
jumper cable start it yet, why not?
or put in a known good charged car battery?
or using any battery charger charge yours?
or buy a new battery, (if rich)

if it cranks and wont start?
check spark x6 (scan it yet?)
if sparks ok try test fuel!
if test fuel fails 100% see bad belt below.

EVER REPLACE THE CAM BELT?
if not and over 60k on the last one
the belt is doomed, living on borrowed time.
got the V6?

Cant start changed fuei filter wires and pluge


check the fuel pump. You can start it and have someone listen by the tank for a 1-2 second hum. If you hear nothing you either have a bad fuse or a bad fuel pump. If the fuel pump is bad you will have to remove the tank.

93 trooper engine not turning over. is getting gas, new fuel pump and fuel filter on it. Is getting fire, but wont turn over.


Use a few squirts of starter fluid directed into the air intake. Remove the air cleaner if you wish in order to get a straight shot into the air intake. If it still will not start, you may want to have your battery checked, along with your charging system. Joe

Engine runs wild with white smoke


If its a 4JX engine then its injectors and seals at fault dont run it any more cos it may blow up - like rods through the side !
The diesel is going straight into the engine without being injected and as the fuel lift pump is mechanical it wont stop on the key .
Should be under isuzu warranty though they are doin that repair on 1998 Troopers over here for free .
