Protest Against Isuzu Trooper 2003 (PAIT)

[4JGtootsie]

Oh Ok, so there's indeed an EFI version then. Does it perform better? I'm curious how the EFI was implemented. I'm assuming the only difference is that the firing of the jets are done electronically instead of mechanically so the lines to the injectors and the injectors themselves are still the same, am I correct?

You are correct, instead of putting so many sensors around the engine the pump was the fall guy since it has full knowledge of timing, fuel metering and engine power. The PCM needs the information about engine speed and power for shifting. The pcm, ecu and abs needs each other to make accurate calculations.

[Mayumi]

So how is the performance compared to the purely mechanical driven engine?

[4JGtootsie]

Mas suave ang acceleration but i cant directly compare because automatic is what i tested and i use a manual. Never tried it at high speeds though, but i heard 170kph based on bighorn tsikoteers claims.

[Mayumi]

Ok, that's interesting. Not so particular about top speed improvement but more of smoother operation and improved fuel consumption. That would qualify for a "nice to have" retrofit.

Thanks,

[4JGtootsie]

Apologies for the late reply.

Its not that simple. EFIs usually are drive by wire (no accelerator cable) where as the mechanical pumps use accelerator cables. Some sensors for vehicle speed should be integrated to the EFI electronics. I also think that they have a small computer box where all info are computed and then fed to the pump.

Sir Jake has a good picture of a VE pump for a 4jg2. An EFI pump has electronics and several wires on top of where the cable/pivot is attached.

I'll post a picture of an EDC (electronic diesel controlled) VE pump as soon as I receive one.

By the way, has your scan tool arrived? Was it able to do a thorough scan on the Isuzu Trooper?

Dumating na po. Sinubukan na namin sa Trooper ni t2ern. Nabasa niya yung protocol but it only says no DTC stored/link. But according to the icons the scan is already powered by the ecu and linked. Brain storming kami on the possible reasons. Need to try it sa V6 gas trooper to see if same result.

whew.. really took time to read this.. kasi isa sa mga choices ko ang trooper.. balak ko kasi mag diesel this year.. buti na lagn me nag post nito.. so fieldmaster na lang siguro ako

Re; EFI Retrofit. I see what you mean so meaning there are no retrofitting kits available.

Btw, mausok parin pala unit ko after the nozzle change, medyo mas malalim nga lang. and confirmed na walang fast idle actuator. Most likely somebody took it out. I have to compare with another unit to restore it.

Dumating na po. Sinubukan na namin sa Trooper ni t2ern. Nabasa niya yung protocol but it only says no DTC stored/link. It is possible that no faults or DTCs (Diagnostic Trouble Code/s) are present on t2ern's engine. Try to simulate a fault by disconnecting any sensor. Your scan tool should detact this as a fault.

But according to the icons the scan is already powered by the ecu and linked. Brain storming kami on the possible reasons. It is possible that software for the Isuzu Trooper is not included with your scan tool. Read your tool literature to see inclusive software. Need to try it sa V6 gas trooper to see if same result.[/quote]

Good luck 4JGtootsie. And please update me.

[4JGtootsie]

We will try to simulate that sir. The scan tools literature has GM/Isuzu try namin on a US trooper or rodeo gas, to determine if can really read codes of US market vehicles. It is suppose to read ISO9141,keyword2000, J1850PWM/VPW and CAN.

Babalitaan namin kayo once we have progress.

mukhang OT na yung nababasa kong thread...
anyway, i just brought my 2003 trooper sa casa last jan29 for a 60Tkm check & have it check also for oil leak. (may tumutulo sa garahe ko last jan 28...) 'though patak lang ang oil, dinala ko na agad sa casa though 59+km pa lang...
On that day also, the service advisor called me up… may (konting) halo na raw yung langis at krudo & they have opened the injector & advised that o-rings must be replaced. I told my service advisor about this thread but he insist that normal talagang pinapalitan yung o-ring every after 50-60Tkm.
now that i got my new trooper w/ new o-rings replaced, i'm thinking of sending email to isuzu phil. for a refund on this (just like AV8OR5 have done). Although the cost in replacing the o-ring is low, saying din ito…hehehe
Parts replaced were as follows:
Gasket (o-ring) – 4pcs =P 421
Gasket Fuel in -4pcs =P 293
Red Silicon Gasket -1pc =P 120
labor =P 937
total =P1,772

now I’m satisfied again with the performance of my trooper…
parang bago ngayon… ang bilis humataw…wala pang usok na tulad ng dati…
pinababa rin pala nila yung muffler for cleaning costing P312.
Kaya lang ang mahal ng 60Km check… palit lahat ng oil…including ATF & LSD.
I hope aabot pa ito ulit ng another 60TKm….
Wala pa akong magustuhang kapalit na SUV kaya dito muna ako sa TROOPER…

Maganda naman ang crdi trooper kaso nga lang maselan talaga. When I drove the trooper of my friend, grabe ang lakas talaga!

[cta2]

good to hear benny 010

seems they have a solution... much better than no solution... and the price seems fair

My trooper is also 03 model... waiting for my car to breakdown, due to the bad rep... but until now no problem...

BTW - our trooper is featured in topgear this month on their 2nd hand column... good review considering the bad rep

Got to read it. White trooper euroversion. Maganda!
Just be observant on the changes in terms of exhaust, temp, power and MIL and dont prolong bringing it for service.

IMO, its all advertisement, not so reliable in real life sense.

no doubt on the power..lakas tlga.

good choice....i would have done the same in 03 if i only knew. again, 4jx1 lang and not the other versions.

sir, I never got a refund on the O-ring. i just availed of their parts like injectors, rpcv and rpcv sensors that was given to me "act of goodwill". but the labor cost borne by owner. the new owner shouldered the labor, i hope the car is doing fine, I haven't received a call or text regarding my old ride.

i hope that your troop will last another 60k km or more.

totally OT na ang topic previous. i suggest to create a new thread if not related to 4xj1 problem or protest, its becoming maintenance repair 101 for trooper and has nothing to do with the threadstarters goals. my 2 cents.

Hello Guys,

I wish to share some information with you in hopes of waking up other trooper owners who are unaware of the problems with their truck. I have documented my experiences and sorry in advance for the long post.

MY CARS SYMPTOMS:
1. The engine has extremely bad power and it’s getting worse, if I go uphill I can only speed up to 10-20Km/h. And can not reach more the 1700-1800Rpm.


2. The Engine performs a bit better when it’s cold, but still with very low power. And as the engine heats up, I get strong vibrations in my gearbox. The idling is also inconsistent and rises and drops without reason. The Rpm can falls to 4-500.


3. As days progress, my engine turns off, and sooner or later I can’t start it at all. I’ve been towed 3 times already so the problem is quite obvious.

[Magnum27]

* My Trooper has been diagnosed and repaired 3 times in I.P. (Isuzu Pasig) starting 27th November 2007 until 26 January-2008. The Supervisor at IP keep on telling me that there is absolutely no problem with my injectors. They claim that they are aware of the injector problems of some Troopers. I.P. also says that the serial number found on my injectors belong to the good ones so I need not worry. However, my car breaks down so often and with the same symptoms makes me think that there is a conspiracy to conceal rather than repair the defective troopers. I have been asking IP to get the serial number of my system and prove on print, that my injectors are part of the good batch but nothing has been printed so far. I need proof! IP must have a record of these good and bad injectors. Right?


Parts that have been changed by I.P. and which I have paid for in CASH


-Rail pressure control valve
-Rail pressure sensor
-Gaskets
-Sleeve O-rings 2 times in 2 month!
-I had 3 oil and filter changes in less then 2000km because of this!
++ Some other things


I’m up to around 35,000PHP and many days with out my car and lot of WALKING in Manila pollution!


The third time Isuzu said that the injector needs to be cleaned, and so they did. They keep on telling me that the bearing in the turbo is defective and only gives about 60% of full power. I.P. wants to replace a new Turbo for 100,000PHP.


I am very skeptical now and unwilling to pay for further repairs until IP is sure about what is broken. After each of the three Services on my Trooper, it is performing well for a couple of weeks, my problem comes back again and the nightmare begins again.


Wake up Isuzu, hundreds of other Trooper owners have the same problems and symptoms and I have been meeting many Trooper owners who confirmed the problem exists, and they have an injector problem and not a turbo problem. How is that for a conspiracy?

Please take a look at these forums in case your company is unaware:

http://www.itocuk.co.uk/forums/viewtopic.php?=&p=45902


How can the turbo system be a problem, Is the turbo going on and off or what??? Why is the car performing well after each service for a couple of weeks? My Troopers Odometer reads 48000km and I already have a Turbo problem?


Can anyone recommend a service center that can take care of this problem? Obviously I.P. can't get this right even after 3 tries.


Is there a more skilled Isuzu service center in Manila? Or please suggest what I should do since I can’t drive my car if it is this unreliable.

So we all know that Isuzu Philippines has been helping some Trooper owners already and covered the costs to fix this problem after many complaints.

We are also aware that there have been major recall order of Isuzu Troopers in many other countries such as New Zealand and many other European countries etc etc. Again ! Isuzu Philippines, take your responsibility like rest of the world please!
No smoke without fire as they say.

[SIZE=3]My plan of action:[/SIZE]

[SIZE=3]I am not one to make threats but this is very frustrating. Isuzu Philippines has to take responsibility as well and if they are hiding something and don't wish to help me, then perhaps a dedicated attorney will help make some noise. How about sending our dearest friends in Manila Bulletin, Philippine Star, and other papers with consumer advocacy writers who will spread the bad news to our Filipino brothers. A protest Against Isuzu Trooper 2003 (PAIT) we are many Trooper owners in the Philippines with the same problem and we can help each other in the Isuzu Revolution! Right should be right![/SIZE]
