moxy 617 Posted November 7, 2012 Report Share Posted November 7, 2012 Hope somebody whos had or worked on an isuzu trooper can help me out, my feckin brain is frying. Trooper 3L V reg Injector went down so went to isuzu to diagnose and replace, however since the injector packed in it became a right cow to start. No problems on main dealer diagnostics other than injector issue. Once you get it started it will run like a dream all day, start stop fine, pulls well all tickety boo. Leave the cow for any length of time, say 8hrs plus and you can forget it. My mates trawled the isuzu forum and had some helpfull replies but non are solving the problem. I have replaced the glow plugs, by passed the fuel filter and installed inline filters so i can monitor if the fuel level drops, non return valves on both fuel feed and return, X2 new batteries, installed a secondary fuel pump with a good flow rate. checked all the wiring, fuses and relays. Serviced just before injector went. There are no visable leaks. When trying to cold start it chuggs out white unburnt diesel from the exhaust so juice is getting through, just not popping and banging although compression seems ok. Now heres the interesting thing, a sniff of good old easy start and i mean the slightest sniff and it chuggs up just fine. Anybody got a clue?? Driving me in bloody sane!!!

jamie mc 168 Posted November 7, 2012 Report Share Posted November 7, 2012 Starter on the blink not throwing it over fast enough may be ?timeing Quote Link to post Share on other sites
mally 832 Posted November 7, 2012 Report Share Posted November 7, 2012 There was a factory recall on that model, regarding the injectors and the pump. Check with the dealer to see if it's been done mate. My mate had the same problem and when he phoned the dealer they asked for the reg number and told him it hadn't had the work done and booked it in and did the work free of charge.

Chid 6,603 Posted November 7, 2012 Report Share Posted November 7, 2012 did all the injectors get changed? Quote Link to post Share on other sites
moxy 617 Posted November 7, 2012 Author Report Share Posted November 7, 2012 The S/N was after the recall date and just the one injector was changed. Plenty of balls in starter. Problem only occurred when injector went down. Cheers Quote Link to post Share on other sites
Chid 6,603 Posted November 7, 2012 Report Share Posted November 7, 2012 maybe one of the other injectors is down? Quote Link to post Share on other sites
RossM 8,142 Posted November 7, 2012 Report Share Posted November 7, 2012 Do these injectors need coded? If so was it? Quote Link to post Share on other sites
moxy 617 Posted November 7, 2012 Author Report Share Posted November 7, 2012 Well I won't be too impressed if after £450 they didn't do it!!!! But I can't see it being that. Once it's running it runs. It's getting the fecker started from cold Quote Link to post Share on other sites
Tam O'Void 297 Posted November 7, 2012 Report Share Posted November 7, 2012 Glow Plugs ...not holding enough Amps....Test the Glow Plugs again .mine were faulty ..replaced ...no prob since ...Ford tho .. Quote Link to post Share on other sites
Guest scramble Posted November 7, 2012 Report Share Posted November 7, 2012 Sounds like the fuels not atomising correctly if a puff of easy start gets her fired up????. maybe get the other injectors ultrasonically cleaned? i think its around £45 a set. cheaper option than changing the lot.

It's getting the fecker started from cold but if the injectors arent spraying right it can make them harder to start , but run ok .. id get them checked as it sounds like youve done everything else Quote Link to post Share on other sites
smithie 2,443 Posted November 7, 2012 Report Share Posted November 7, 2012 i had a patrol like this and was sure injectors were on the way out. i had very sililar problems with the starting and it turned out to be my battery. i thought the motor was turning over fast and ruled out the battery but eventuly i went to halfords for a battery and that was the end of it.

RossM 8,142 Posted November 7, 2012 Report Share Posted November 7, 2012 Split vacuum hose or intake hose will make it difficult to start too, what's your fuel lines like? Even a slight diesel sweat will allow to draw air and make start up difficult. Is the egr valve operating correctly? Just of the top of my head. Quote Link to post Share on other sites

Even a slight diesel sweat will allow to draw air and make start up difficult. Is the egr valve operating correctly? Just of the top of my head. All valves working correct and no split hoses, that was one of the first things i checked, as i said, i used a clear bowl in line fuel filter and monitored the fuel levels, it was a hunch that the diapraghm in the main fuel filter was allowing air through but by passed and ruled it out. Scramble, im leaning towards your way of thinking as it sounds plausable, other than back to the injector issue most other avenues have been explored, Whats more anoying is i bet my bollox its something or nothing. Cheers for the replys so far lads Its good to try and talk it through with somebody with fresh ideas, im starting to go more crazier than normal, talking to myself over and over about it for over a week now Quote Link to post Share on other sites
Baghdadnights 150 Posted November 7, 2012 Report Share Posted November 7, 2012 I would go with starter as well isuzus rely on a high fuel pressure if the engine is not spinning fast enough you won't get the pressure slight wiff of easy start will fire the engine making it turn faster Quote Link to post Share on other sites
