medusan Posted November 18, 2012 Share Posted November 18, 2012 Hi, I have just swapped my TD5 Discovery 10P engine for a TD5 15P from a Defender (apparently). It is all plumbed in and wired up. After a lot of fuel purging it started, ran very rough for about a minute and then died. It did this a couple of times. I know i have to get the new injectors coded into the ECU (NNN model) but i do not have access to a Nanocom/hawkeye or testbook. I borrowed my brothers SNAP-ON Ethos but that unfortunately only reads the codes and resets them by the looks of it. I have the codes of the injectors ready to put in. I was wondering if there was anyone in the Gloucester area who had access to a Nanocom or such and would be willing to help me out. Cheers, Medusan.

Ally V8 Posted November 18, 2012 Share Posted November 18, 2012 It would be good to get the correct codes edited into the ecu,but thats not why its stopping.Does the pump scream like its got air in it when you try to restart ? The correct injector codes will just make it run smoother. Quote Link to comment Share on other sites More sharing options...
medusan Posted November 18, 2012 Author Share Posted November 18, 2012 It seems to purge the air out of the fuel system - we turned the ignition on and off for about 10-15 times and then it fired up - however to get it to fire up again we had to do the same. My brother who is a mechanic but not a landy expert then said it sounded like what he would call diesel knock and thought it would be sorted by getting the injectors coded so they worked properly - problem is it is a 15p engine from an unrelaible source i have found out - i was told it was running when it was taken out. Just really want to rule out the injectors.. Quote Link to comment Share on other sites More sharing options...
Off Road Toad Posted November 19, 2012 Share Posted November 19, 2012 I had to replace my cylinder head after I bought my 'good engine' and the replacement head was second hand- a bit of a risk. After fitting I had exactly what your getting, it would purge air out and run for maybe 2- 4 minutes. Turned out the new head had cracks at the injector seats and combustion gases were getting into the fuel rail. Not sure if a 15p engine works in the same way as the fuel rails are different.

medusan Posted December 1, 2012 Author Share Posted December 1, 2012 In the end i went out the next day and tried the turn on/run fuel pump, turn off, repeat, exercise several more times and it fired up and ran ok. I then turned it off after about 5 mins and it fired up fine again. I guess i had not purged all the air out of the system. A fellow D2 owner from the D2 Boys Club forum then came around with his Nanocom and we coded up the injectors to the ECU and it ran even sweeter. I now also have a an EU2 map to put on my ECU(NNN) which again should hopefully have it running even sweeter. Lesson learned..be a bit more patient....nice to have finally proven that with a little tweaking you can replace a 10p with a 15p engine!
