and that keeps making me feel tied

it was an x3 box, you would have to change both diffs as the transferbox is not a true diff

as someone who drasticly changed hes drive train (manual box) in a l322 i looked at changing diff ratios, but decided against it as too much work for little gain, several things came from it, the forum was split about doing it ( one member was very against it and another wanted details on how i...

i went through this last year low pressure and no start was about to change the high pressure relief valve at the back of the high pressure pump when a diesel engineer told me to do a leak off test, one faulty injector later runs as sweat as, you wont get the high pressure if its leaking back...

if he has a pressure sensor issue he wont read any pressure with diags,( and an immoberliser issue in the ecu) id go for the leak off test easy to do, its fuel air and compression despite all the sensors

but that will only tell him he has a pressure problem which he already knows

he needs the right software for that, besides hes already been told theres no pressure, just hasnt diagnosed were its going, becoming a shot gun repair ( unnessesery ecu mod )

there are lots of reasons why you cant register fuel pressure, the imoberliser isnt one of them, there are 3 pumps in the system any of which could cause no fuel pressure then there is the fuel pressure relief (mechanical and not monitored) and faulty injectors, the fact you have a code from the...

diesel is crank disabled, petrol is fuel disabled

i had just one faulty injector which prevented the fuel rail from getting to pressure, no pressure and ecu doesnt fire injectors

you dont need to have it running just cranking for a leak off test, there are plenty of utube videos on how todo it plus a leak off kit on fliebay is about £35

i would do a leak off test before doing the fuel sensor as a faulty injector stops it starting ( and if it was cranking it wasnt the immobiliser)

there is a whole sequence of events that have to happen before the diesel will start (cant say about the petrol) any one of which would stop the starter from working

i some how think you have been barking up the wrong tree with the ecu being the problem

well that solves the problem of the clicking on my friends one, let us know how you fix it please
