mickanles Posted September 16, 2014 Report Share Posted September 16, 2014 Hi, Are there any Mitsubishi tecs on board ?, Have recently bought a cheap 2002 shogun sport 2.5 which is nightmare to start either hot or cold, Drove home 200 mikes ok. Just keeps cranking over and over but will eventually fire up, No excessive smoke, Then there is no response from throttle pedal for a minute or so. It has had tank sender and pipes, thinking it was pulling air in. I have heard of failing injector pump front seals , Not allowing fuel to be drawn up from lift pump part of pump. Was thinking of feeding pump straight from a raised can to eliminate tank to pump supply. Other than that booking it in for a diagnostic check, Any ideas or help taken on board.

bluesj Posted September 16, 2014 Report Share Posted September 16, 2014 Yeah try this lot http://www.l200forum.com/ ok not sport but the same engine. Sounds like it may be fuel pump seal, a common fault. try pumping up the primer pump before you try starting. Quote Link to comment Share on other sites More sharing options...
aauser Posted September 16, 2014 Report Share Posted September 16, 2014 Try checking for diagnostic codes and it's possibly cam sensor issue as it needs a fair crank to determine no 1 on only crank sensor Quote Link to comment Share on other sites More sharing options...
Cannon Posted September 16, 2014 Report Share Posted September 16, 2014 Best to get the codes read, but it definitely sounds like a fuel supply issue. Quote Link to comment Share on other sites More sharing options...
Paul223 Posted September 16, 2014 Report Share Posted September 16, 2014 Yep try the raised tank method first, that should rule out pipes and pump seal, if the engine then starts ok try some clear hose between filter and pump, if it's drawing air in it'll be very apparent, then try the clear pipe between filter feed pipe and filter, doing this will rule out the filter head or corroded steel pipes on the chassis. No air and starting fine would suggest pump seal. Update with what you find Quote Link to comment Share on other sites More sharing options...
al4x Posted September 17, 2014 Report Share Posted September 17, 2014 Lack of compression would also be a possibility, any signs of water overflowing the header tank? Quote Link to comment Share on other sites More sharing options...
mickanles Posted September 17, 2014 Author Report Share Posted September 17, 2014 (edited) Thanks for replies, No loss of coolant, no overheating, Have a day off tomorrow so will try a raised tank and go from there.

mickanles Posted September 18, 2014 Author Report Share Posted September 18, 2014 Quick update, Ran with a raised fuel tank, no better. Had fault codes read and came up turbo over boost , Possible sensor fault? Tried local fuel injection centre and suggested to run with a clear feed and return pipe on pump, Check to see if there is air on the return but not feed as may be a pump fault. Failing that maybe a compression test as has been suggested. Quote Link to comment Share on other sites More sharing options...
Paul223 Posted September 18, 2014 Report Share Posted September 18, 2014 Over boost won't cause your starting problem, check all the induction /intercooler hoses for splits / leaks Quote Link to comment Share on other sites More sharing options...
fruitloop Posted September 18, 2014 Report Share Posted September 18, 2014 Glow plugs? Quote Link to comment Share on other sites More sharing options...
onatangent Posted September 18, 2014 Report Share Posted September 18, 2014 The overboost fault code is vague as it gets. My Audi had overboost reported and was due to egr being knackered. Easy to spot with sooting. handy if you can do live engine data logging to see map,timing, maf, fuel metering etc. Quote Link to comment Share on other sites More sharing options...
Paul223 Posted September 18, 2014 Report Share Posted September 18, 2014 Yeah over boost does not mean it's creating to much boost but rather boosting more or for a prolonged period without the boost pressure climbing to suit, at a guess your egr was leaking boost pressure hence the over boost code Glow plugs? Indeed easily over looked check em out and supply voltage / current Quote Link to comment Share on other sites More sharing options...

On my L200 Boost sensor failed and if I remember rightly it went in limp mode Quote Link to comment Share on other sites More sharing options...
onatangent Posted September 18, 2014 Report Share Posted September 18, 2014 Easiest way is to run live data, can eliminate a multitude of sensors. As I said about my egr, gave boost spikes, boost frequency valve drop offs, soft intermittent limp mode. Never had a prolonged crank start issue though was just a bit longer than the norm. Even with seized vnt that I had to decoke. Ideally get the diagnostics hooked up and try starting it while looking at the things that have been mentioned here, pump priming, rail pressure, inlet temps as might think its cold start condition when its not or vice versa and any other measuring block of use.

al4x Posted September 19, 2014 Report Share Posted September 19, 2014 It's the 4d56 engine I'm assuming so relatively uncomplicated. Personally with starting I would check glow plugs as mentioned. If it runs fine once started then it's quite possible, my last l200 was fine till 3 didn't work then played up. Dead easy and free to check before going any further.

mickanles Posted September 19, 2014 Author Report Share Posted September 19, 2014 Has had recent glow plugs, relay, all working ok. New tank sender and pipes Tryed it today and cranked over for ages and eventually started, would idle ok but no response from throttle. Will try clear fuel pipes tomorrow on feed and return and check for any air Quote Link to comment Share on other sites More sharing options...
Paul223 Posted September 19, 2014 Report Share Posted September 19, 2014 That sounds so much like air being drawn in Quote Link to comment Share on other sites More sharing options...
Steveg01 Posted September 20, 2014 Report Share Posted September 20, 2014 My l200 had a similar issue and found that the timing was out. Quick check by the local garage and started every time Quote Link to comment Share on other sites More sharing options...
mickanles Posted September 20, 2014 Author Report Share Posted September 20, 2014 Today I removed all glow plugs and checked on a battery, 1 knackered so replaced, Fitted clear fuel lines and ran up , no air visible on feed or return. Still a **** starter. Will check timing tomorrow, Failing that will have to buy a diesel engine compression tester as my petrol tester will not handle/read the higher pressure , Which I hope to see. Hope to sort this out sooner than later. Thanks for your replies Quote Link to comment Share on other sites More sharing options...
Paul223 Posted September 20, 2014 Report Share Posted September 20, 2014 Did you check power supply to glow plugs Quote Link to comment Share on other sites More sharing options...
mickanles Posted September 20, 2014 Author Report Share Posted September 20, 2014 Yes relay working, 12 volts at buzz bar , Quote Link to comment Share on other sites More sharing options...
Paul223 Posted September 20, 2014 Report Share Posted September 20, 2014 (edited) Ok With a cold engine slacken an injector or two and crank it over, do you have lots of diesel spill immediately or not Edited September 20, 2014 by Paul223 Quote Link to comment Share on other sites More sharing options...
mickanles Posted September 20, 2014 Author Report Share Posted September 20, 2014 OkWith a cold engine slacken an injector or two and crank it over, do you have lots of diesel spill immediately or not Will try this in the morning and update.

Paul223 Posted September 20, 2014 Report Share Posted September 20, 2014 (edited) If you do (have plenty of fuel) then move onto compression test Edited September 20, 2014 by Paul223 Quote Link to comment Share on other sites More sharing options...
mickanles Posted September 21, 2014 Author Report Share Posted September 21, 2014 Checked timing today, crank, cam and pump all on the pointers, Cracked off and pulled back injector pipe unions, wound it over to find very little fuel delivery / squirt. Not 100% sure what to see but seemed very little to me. Quote Link to comment Share on other sites More sharing options...
