Question about 1998 Isuzu Trooper

Trooper 1998 fails to shift, think ecu is missing

I have an Isuzu Trooper 1998 chasis and engine. It has been in storage but is now running. It seems like there is a missing ecu since the automatice 4wd shift on fly (lever) fails to work well and seems to lock in 3rd with it set to 2wd. I have two ecu units Delco DK1080?8 or DK108008 and a 16205439 (3.25 AUT TCM-6). What is the 3rd ECU I need? The Isuzu manual (3500+ pages) for 1998 shows a transfer case ecu. It is not a TOD model Trooper. Prior to storage it worked fine and drove well.Regards,
Thomas

    We changed all the fluids, cleaned the gas tank, new fuel, changed all filters, etc., changed sparkplugs, changed injectors
    Focus on ecu's because some dangling wires, my memory of 3 ecu's when we have only 2, and trying to read and understand all the details in the Isuzu manual.

Testimonial: "This was good check point, but I think we should be ok unless the fluids in the transmission are wrong. I will check tomorrow."

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?

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.

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,

My 1998 Isuzu trooper when cold it has delayed shift fom first to second then it shifts ok


sounds like a dirty oil or filter problem. It is taking this long for the viscosity of the oil to change to allow shifting. Run fault codes as well consider having an oil change done on the transmission ( oil colour should be cherry red not tan coloured.)

My 1989 Isuzu Trooper will start but not idle or run. I found a shredded belt laying across the engine but all the belts are intact and running on the right pulleys. Any ideas?


Double check the belts. If the alternator belt has failed, the engine will not run. The alternator is located towards the bottom of the engine, and the pulley is easy to miss, as it is sometimes painted black.
