Question about 2002 Isuzu Trooper

1 Answer

I have a 1999 Isuzu Trooper that will crank but not start. I have tried everything in the world to get it fixed and have failed. I have checked the timing, compresson, new computer, new crank sensor, new map sensor. This vehicle was driving down the road and died. I towed this to my shop and the computer has no codes on it. I checked the testing procedure as per On Demand repair progran and i have no injector pulse, no fire on the coils, and the crank sensor when checked by the snap on computer showes no rpms when cranking over. The owner brought me a new computer with cal emissions and the vehicle had fed emissions whould this have anything to do with it? Any help on this would be great

Where is the emergency fuel cut off switch located on 1999 Isuzu trooper


no engine stated..
i guess you like to search on rumors?
there is inertial switch. but no country stated nor engine nor drive line.

first check for spark not fuel
the ECU cuts Fuel anytime it sees spark fail (3 ways)
to stop TV like crash and burn,
check for spark if its good x4 or x6 , (depends on engine size)
and if that is good, check that engine runs for 3 seconds on test fuel, if thats good? then we check fueling system.
see?
we have posted this answer on ISUZU vast times.
and not one poster ever once, told what engine is there or they country.
or insert scan too
crank for 5 seconds, Got P03xx codes, that is the BINGO for no starts, right? ever scan a car? its a cheap tool all mech have.
and all savvy DIY have.

but ive not had all engine options, on a 1999.

so will look yours up, 1999 and pretend USA model. (not canada)
some isuzu do have this red electric switch
so lets see if the 99 usa has it.
that means if its missing in the pump page, its not there.
drum rollllllll
no switch. 1998 usa trooper.
end easter egg hunt 1200.

the pump runs off the fuel pump relay DIRECT
the relay IS ONLY controlled by the ECU,

I have recently purchased a second hand isuzu trooper model 1999 with manual transmission..everything goes on smoothly until one day it suddenly stopped as if it has gone out of fuel and wont start no...


No its not full with diesel fuel this is a common shut off on the isuzu. Plus the valve are always noisy . The crank sensor on those go out easy.This may not be the problem.Go to the back have someone crank it ,or if your hearing is great as you crank it do you hear a hummin noise that will be the fuel pump if you dont then the fuel pump will most likely be your problem.If you hear a humming noise as you turn the key on the fuel pump will not be the problem.Now let check spark. do you have a tach on it (the RPM) if you do crank it if it bounces just a tinytiny bit you have spark and the fuel pump will be the problem. Most common Isuzu trooper failure the ignition module

Trooper will not crank and I don't have fuel pressure The anti theft light blinks and stays solid when you turn the key to start no power to the fuel pump


It thinks you are trying to steal it. Are you using the same key you always use? A qualified repair shop may need to check it for you.

Electrical problem


Check the ignition lock and tumbler and the electrical part of the switch itself. It could be as easy as the plug needs to be pushed in all the way.
