hi i recently bought a project 2005 defender 110 td5 van type body from a local auction which had previously belonged to an electricity company. the vheicle had been cannibalised and lots of parts are missing. the ecu was gone and i purchased another on ebay nnn500020. ive fitted the ecu and with a bearmach hawkeye coded in the injectors. my question is how do i match the ecu to the 10as immobiliser unit. the vehicle cranks but the fuel pump isnt running but the fuel pump relay is energised which could be just a pump problem. im assuming that its a fairly basic 10as thanks john
