1999 Isuzu Trooper - Answered Questions & Fixed issues

before you remove belt time mark on cam gear as well as crankshaft pulley, the timming mark on the pump drive gear (lower gear in this picture) will not line up but thats ok line up the mark on pulley to rear cover at about 12 O clock when the belt is off.

Question edited for clarity. Wrong type of break / brake. Question moved to model category. Check the brake switch with a meter first. Then check headlight relays and fuses. https://www.planetisuzoo.com/threads/no-brake-lights-with-headlights-on-1991-trooper.151493/ https://www.google.com/search?q=1999+Isuzu+Trooper+brake+lights+not+working ..

Sometimes if you write a word that Fixya scripts doesn't like, it won't let you post it. Think of Fixya as your 90 year old granny and what words might offend her. No, I just changed the Category, so your posts ends up in the correct 'filing cabinet'. Some of the Experts only check the Categories that they are Experts in. You weren't talking about an Ariel Car, you were referring to an Isuzu Trooper, so I just altered the category. Your original post just said 'Trooper' (I edited it). All question for vehicles need FULL 'year make model'. If you do that, Fixya scripts will suggest the correct category, but you confused it by capitalizing the word 'Ariel'.. I put a link to to the post in the last message to you. ONCE AGAIN, making Follow-up posts as new posts doesn't work. Posts here are not threaded or linked, so this post has absolutely NO context to your other posts. I only saw this because I am here all day answering and refreshing the feed. All you have to do is click the word 'COMMENT' under my post. Here is the link to all your posts. You just have to click on your name highlighted in blue on any of your posts or by clicking your name top right, and then 'My home'. https://www.fixya.com/users/busybaz and then click on the word 'question' highlighted in blue Busybaz posted a question about 1999 Isuzu Trooper: Here endeth the lesson :>D ..

you have a short disconnect the wiring and test motor

1999 Isuzu Troopers w/automatic transmissions do not come with a dipstick. It is a sealed transmission just like a manual transmission. The fluid must be checked by removing the fill plug. Emergency brake on, engine running,warmed up ,vehicle in neutral. When removing the fill plug ,which is on the side of transmission- at the top, fluid should slightly drip out. If fluid doesnt drip out you need to add fluid. You will need a small hand pump to fill it.

Buy a can of throttle body cleaner take off the air filter box, follow the tube and then spray the throttle body and wipe it out first before condemning the injectors

you can get guide from many sites.. i know few like reliable-store error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered within seconds u can get the access and it's totally illustrative complete

If you have no oil pressure on the dash gauge you need to drop the tin sump under the engine and check the two oil pick up pipes in there . They crack and fall off or the seal goes hard letting in air so no oil pumps. An known fault on the 3.0
The long one is for the engine oil lube ( turbo ) and the short one is for the injection system .
The high pressure pump is only for the injectors.
If you have good oil pressure on the dash gauge then I agree with Guru Ronaldbrains the turbos are poor but ! its 5/30 oil in 3.0 4JX1 engine or you will have starting troubles .

i know a website that has very good manuals online, without expiry i.e. for lifetime. www.reliable-store.com they can help you with this

indicates a fuel supply and pressure problem check and bleed the system have the injectors professionally overhauled by a diesel specialist shop

just have to keep persisting i got the thought that your ebay purchase was a generic kit saying "compatible "with a trooper https://northcoastkeyless.com/1999-isuzu-trooper-keyless-entry-remote-programming-instructions

screws

ever heard of a $5 automotive stethoscope sold in all car parts stores? you can listen to each thing on front of any engine and learn WHO is talking so easy.

I could not find a video or any written instructions, but I did find a free shop manual and it will be in there. It is a large pdf file so allow download time please. http://www.jeepolog.com/UserFiles/downloads/trooper_manual.pdf

no response soso less1:will it slip parked, idling, in drive,footon brake,? then advance throttle and see like 2000rpm but fails and goes why higher?that is the stall test failing,2:fail in reverse, parked?fail only movinggee,,,, can you say more than SLIP?

I had the trooper in for an oil change and emmissions check. Next day, it almost stalled. After a couple trips, it started to stall every time it stopped and I tried to start up again. Turned out, the tubing coming out of the MAF has a hose clamp around it. That hose clamp could freely spin around. I tightened it up. The truck started running better. And after 3-4 trips, the codes cleared themselves. Reading about it, there are a lot more causes, but this was apparently mine. IDK why it was loose. Something at the inspection place. Maybe they did it on purpose because they wanted nearly $80 to replace the fuel filter (a $10 part) and I refused.

why ask us. sure they are incompetent? asking for a blind 2nd opinion? wow. the sender can be tested on car, or tank of floor or sender in hand using any $10 DMM meter ever sold (ohms) the service manual shows how, if They can read, RTM all books sold on all cars tell this, the dash meter too is tested in a very simple way, ask/

the TOD, system needs diagnois the SM covers that, i can paste the whole TOD chapters here. log in to mitchells, and read. google mitichell DIY. the system is complex, it slips a magic clutch to simulate a center differential gear that is not there.
