Solder...I too HTH's.....thanks ever so much for your reply and insight. What troubled me for some time is that I gather the truck has an ecu and the pump has a fpcm (fuel pump control module) As such a ton of water under the bridge got lost in translation with me.... I work in telecoms not cars tho I get the need to get some terminal emulator/interface to program software/ID's if required ...though I not got a clue on what tools Nissan Consult are nor any other interface/diagnostic tool I might need to get my hands on. I bet the syntax/ID code, if required, is like some 16 digit MAC address like what we have on our internet devices at home

So I bought a pump from Ireland and it looks like it has never been installed ...or if so previously then a fantastic recon. I gather the Irish army use this truck and were selling off old new stock to the dealer I bought my pump from....which cost me £1000 not so Great British pounds. Then there was the new timing chain and gasket set. So my local mechanic is anxiousness spends lots more of my cash putting it all together and we end up with a dud set of circumstances ... Coding and or NATS... I do know about not 'cooking' the chips on the FPCM as it needs lots of diesel to bathe in

So am I looking for TB4SE on some label on my trucks ECU or my new FPCM ? Or am I to look at the connector type ... Being a pseudo OBD2.

To this final senior moment I am having in all of this ..... This generous Bosch diesel specialist (not Nissan specialist) I am working with here... He has since stated ... In regard to a Patrol he referenced above that they dealt with (he doesn't have my car as he is many clicks away) ...

He says ......to reprogram the ECU the pump ECU has to be wiped then run on test for about 3 hours to re-map everything which would be £250 approx. These ECU's only have the capacity to be mapped a few times before they need replaced so you might need an ECU kit which is quite expensive ... Like another £500.....

As you may have concluded my mechanic is keen to proceed but not if the car won't start...and the Bosch guy on the other coast has my original dead pump which he declared dead and told me it would be £1800 to recon it... I at a loss on this item ...

Thanks ever for any further insight you chaps can offer ... Do we bang it all together ...spend another UK grand ...it doesn't start and then find myself £3k down and pushing it into the sea and end up using it to anchor my flat head tub ?
