SiWhite Posted April 13, 2010 Share Posted April 13, 2010 Right folks, I need some serious help with this. The TD5 STILL doesn't start. Stuff I've tried so far.... New injector washers and O Rings New injector loom Fuel pressure checked - fine Air in the fuel - checked with clear tube - still a TINY bit when the pump starts New known ECU programmed to injectors and 10AS Faults checked - nothing apparant - and cleared on Nanocom and Rovacom Long tow to rule out the starter Crank position sensor verified with Nanocom Everything works like you'd expect - immobiliser light goes out, alarm light responds to the plip of the fob, fuel pump pumps (bit noisier than I'd expect, but flow and pressure are fine), glow plugs work and engine cranks beautifully. After the tow tonight, there was no smoke from the exhaust and no diesel-y smell from anywhere. The engine didn't even try to start. The only things I can think that might be causing this are; Fuel still not getting to injectors - will a bad fuel pressure regulator cause fuel to bypass the head completely? Noisy fuel pump - but I have flow and pressure so should still be OK? ECU is still showing as immobilised on nanocom (Rovacom has no facility to show immobilisation status) even though immobiliser light on dash goes out ECU is still not passing the 'fire' instruction to the injectors - even they 'click test' on diagnostic Blue connector by ECU - appears in order - could this cause these symptoms? Is there a relay or fuse that will prevent firing of injectors - nothing found in the workshop manual Could someone confirm where the three ring-terminal earths by the ECU go to? All are on the seatbox stud for now.... Please no-one suggest anything about getting a different engine - bit past all that to be honest.....

SiWhite Posted April 14, 2010 Author Share Posted April 14, 2010 Thanks for the offer Dan - I've already put a few folk out of their way helping me out with this. We'll stay in touch about that if you don't mind...? So maybe it is immobilised still? Very curious that the immobiliser light goes out on the dashboard I've got the exciter coil round the ignition and have programmed everything to 'plip immobilise' with Nanocom. Maybe I've missed something and it still hasn't un-immobilised. Anyone got an idiot's guide to un-immobilising a vehicle - have access to Nanocom and Rovacom (thanks fellas....!)

T1G UP Posted April 14, 2010 Share Posted April 14, 2010 Si I'd try another ecu without any of the plip ****e attached. Maybe the ECU just can't handle that? Never had any of that on it before so i'd try another ECU if poss. Have you / do the injectors need to be dailed in? If these things are so easy to pinch then maybe a factory imobilser is not the way to go? Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 14, 2010 Author Share Posted April 14, 2010 Marcus, Thanks for the reply. It didn't do anything when it had the setup I bought from you, so I now have a new ECU, 10AS and exciter coil. Injectors are programmed. The thing that makes me think it may still be immobilised is Nanocom, which still says "ECU Immobilised' despite the plip deactivating the immobiliser light on the dash. How was the ECU running without a 10AS before Marcus? Had the ECU been modified at all? Quote Link to comment Share on other sites More sharing options...
Daan Posted April 14, 2010 Share Posted April 14, 2010 Has it got a crash switch? It might need resetting by pressing it. I think the TD5 has got one. Daan Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 14, 2010 Author Share Posted April 14, 2010 Yup, checked that Dan. Fuel pump won't work without it..... Quote Link to comment Share on other sites More sharing options...
Jurriaan Posted April 14, 2010 Share Posted April 14, 2010 Not that much into Td5s, but a friend of mine had a Td5 90 with problems. Solution was to replace the ECU by a proper Defender one instead of the Disco ECU in it. Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 14, 2010 Author Share Posted April 14, 2010 Thanks Jurriaan, ECU is from a defender. I'm going to replace the fuel pump as it's noisy and see if there is any change....doubt it though.... Quote Link to comment Share on other sites More sharing options...
ARMYBOB Posted April 14, 2010 Share Posted April 14, 2010 my fuel pump on my 2001 td5 is noisy as hell but runs fine, FYI Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 14, 2010 Author Share Posted April 14, 2010 Thanks Bob - would rather spend money in sensible places than replacing things blindly..... Quote Link to comment Share on other sites More sharing options...
yella 90 Posted April 14, 2010 Share Posted April 14, 2010 simon i highly doubt it's the pump i can come down next weekend and bring another loom with me to completely isolate the vehicle ect injector codes will make no odds to the engine starting. if its not getting any signal to the injectors to open if theres no smoke what so ever. you can test the injectors off the nanocom but that doesnt mean anything in signal terms for running. dont go fitting a pump as ive got one spare aswel. let me no what you want to do dan Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 14, 2010 Author Share Posted April 14, 2010 Yowser - great offer Dan, thanks! Through remarkable forum generosity I now have an ECU in the post that will not need a 10AS at all. This will tell me if it is the engine wiring loom or my ECU / immobiliser. If I'm still stumped then Dan's offer would be amazing - SWMBO has said she'll make cake! Pub lunch ahoy!

white90 Posted April 14, 2010 Share Posted April 14, 2010 Nice to see such help offered freely Si I do hope it is sorted soon as it must be a concern till you get it running. Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 15, 2010 Author Share Posted April 15, 2010 Yup, bit of a concern Tony. I've got £7k in a car that has sat in a barn for two months and not moved an inch under it's own steam. Hopefully we'll get it sorted..... Quote Link to comment Share on other sites More sharing options...
T1G UP Posted April 15, 2010 Share Posted April 15, 2010 Si, ECU was standard, was standard in the power train dept aswell. Fuel pumps fine IMO, may sound noisy to you but when shes all together is OK, save your money. "unlocked " ECU sounds the best bet, Dans offer sounds even better!!!

yella 90 Posted April 15, 2010 Share Posted April 15, 2010 had a though today.... theres two types of 10as box and IIRC the early one doesnt support plip ect but i will stant to be corrected happily Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 15, 2010 Author Share Posted April 15, 2010 Update - no update! Just come off the phone from Porny who is a LEGEND and is driving down on Saturday morning in his TD5 to sort the old girl out. I'm also going to get my 'spare' ECU turned into a standalone unit i.e won't need a 10AS. This will be a deep emergency bit of kit should anything ever go wrong in the future. Fingers crossed, on saturday lunchtime Porny and I will be in my local with big cheesy grins! Quote Link to comment Share on other sites More sharing options...

tonycan Posted October 20, 2010 Share Posted October 20, 2010 This was a very interesting read. So glad that you got your td5 running. I was struggling with my td5 last year also ever since it went under up to the roof for 12 hours in the big flood in Manila. I tried everything until I finally found out that the used ECU I ordered on ebay was defective and all it needed was a brand new ECU I bought from Singapore. I also sought help from Porny but he wasn't online around that time. Cheers! Quote Link to comment Share on other sites More sharing options...
