hi, i have a 2006 land rover discovery 2.7 TDV6 with manual transmission..

the cam belt has recently let go at 113k miles so i decided to change the engine.. which was a lot bigger job than i expected but its in and done.

the only TDV6 engine i could get was from a 2009 jaguar xj with 36k.. its a twin turbo so i stripped the engine completely to a bare block which is identical to the landrover block and built it back up with all the bits from my original engine.. turbo, injectors, egr and pump etc.

now when it was finished i primed the fuel a few times, checked everything over and gave it a go.. it started straight away and was running brilliant!!

three injectors werent sealed properly but it was still running lovely.. it was running for about 30-40mins while i tidied up and topped coolant up etc.

just as i was about to get in and give it a test run it developed a bad missfire on more than one cylinder (poss three!) so i switched it off.. it has never started since :(

i have read the ecu with a snap-on solus and there were loads of code from when the cam belt went so i reset them and turned it over.. no start still but only got the code..

P062D - Fuel Injector Driver Circuit Performance bank 1

i cannot find any info about this code.. landrover are very unhelpful and no-one seems to be able to work with the TDV6 near me.. so far ive carried out all basic tests..

-wiring, all plugged up, got fuel etc.
-rail pressure is good about 40,000kpa
-it will start with easy start
-new injector copper washers
-there is fuel pressure to injectors
-injector leak off test

it seems everything is good and working apart from there is nothing telling the injectors to open/close?? ive gone a far as taking the injector out and fitted it upside down out of the head.. when i turn it over everything is fine but the injector just doesnt fire!

has anyone else ever seen this code or had a similar problem? sorry for such a long post but i wantg to provide all relevant info first off. any help will be greatly appreciated.. today im going to do the same on the other bank to see if any other injectors are firing (i ran out of light yesterday) as the code suggests 'bank 1' im thinking the problem is only on one side.

thankyou for reading... A4RON.
 
did you fit the injectors in their orignal position ? from what I understand they are coded to each position in each engine and the ecu works from the individual characterstics of each injector
 
From what you have discribed it sounds like the wiring loom to the injectors or even worse something in the ECU has gone and it is not providing power to the injectors.

Can you use the wiring from the Jag engine. I asume that the injector loom can be removed like the TD5?
 
thanks for the reply.. im sure the injectors are in the same positions as they were in the other engine i did think that would be important, unfortunately no the loom is not separate its quite a large engine loom also different to the jag loom.. i would of thought if the ecu had gone down id be getting lots more problems coming up? also this P062D code isnt even listed in autodata etc. i cant find anyone who knows how to deal with it

From my experience, with the driver circuit, it's usually an injector failure but that said if your runing the Jag loom that may cause conflicting issues, not the answer I know but thought I'd chip in with that!
 
ive only used the block from the jag.. Everything else is different. I dont have another loom to try so looks like im gona have 2 spend some time checking it over then ill have to check the ECU.. Someone must of had this code before there isnt much that can cause complete shut down!
