Evening , I'm planning on swapping all four injectors on my 3 litre trooper to either eliminate or cure the misfire issue I have .  Am I right in thinking that the engine will still start up without setting the injectors up on tech 2 ? ? Many thanks in advance for any help

Ps: it will most probably start no problem without coding - but do not run it for long without getting them set.
If they are set to run lean you could do damage.

if they are the same grade then no programming is needed

You donít really get a choice of what grade you get sent hence you get them coded in after fitting

Hi,

Iím not sure if Iím posting this into the right section, if not, appologies for that.
I own an isuzu trooper 3.0 diesel 4jx1 2002, and I want to replace the fuel injectors.
The only places that Iíve found to buy new injectors are from alibaba/aliexpress.
Did anyone buy these from china market? If yes, are they genuine or aftermarket? (The price is ~ 270$).
Are they good, does the engine start after installing them out of the box or they require some programming?
Also, if anyone bought them, can you point me to the seller?

Any advice/ experience in buying the fuel injectors is more than welcome.

Thanks,
Claudiu

Hi, personally I wouldn't touch anything that isn't genuine when it comes to the injectors . Also beware of buying second hand unless from someone who has tested them and gives you a money back guarantee . I don't have any idea where to get some injectors from but there are gents on here that do . It's my understanding that after fitting  new injectors the engine will start as normal but they need coding afterwards ( need to tell Ecu of the injector grades ) . There is a sticky on here that tells you which grade the injectors are from the code on top of the injector and also you should be able to find a walk through/ information on how to change the injectors . Good luck

Hi Buz,

Thanks for your reply, I want to avoid buying second hand injectors (I've already changed the injector from slot 1,  4 times by now). As I previously said, I want to buy them from aliexpress, they claim that the injectors are brand new and genuine, but I wanted to know someone's experience in buying it from Chinese market (my concerns are: will they delivery the injectors, are they genuine, will the engine start after replacing the old ones with the new ones..etc).

Thanks,
Claudiu

So I finally got round to replacing the injectors in the trooper. Everything went well until I removed the rocker cover and found two non original zip ties holding the ORPS connector on !!  Removed the zips ties which were like glass and was a sign of things to come. The injector harness clips shattered on each injector regardless of how careful I was. Luckily I had a harness off the old car . Refitted replacement injectors and everything else , cranked it over for about 30 seconds and it started and runs like it used to. Just need to take it to our local dealer to have the injectors and ORPS dialled in ( injectors were 49 now 37 )  . Many thanks for the help received along the way.
