Hi all Have above vehicle in at the moment, won't start when warm. When its cold it starts fine and will run perfect, when its warm it runs fine its just when you turn it off it won't start until its cold. Fault coded engine, immobiliser, instrument panel, and body control module all saying no fault codes. I've looked in the archieves and mentioned the pump control unit so i took that apart and looked at the soldered joints and they look fine. Crack an injector off and you get good flow of fuel, getting an engine and a pump speed signal in live data, but strangly the engine and the pump speed are the same. Should that be the case i thought the pump should be half engine speed? Ive also checked earths and powers to the engine control unit and the pump control unit and all are good. Any advice would be most appreicated.
