i changed the pump as the old one had chewed its self to bits and i had no fuel pressure 400kpa is what it read up as on my diagnostics machine and it wouldnt start unless towed but when you did tow start it it sounded like a bucket of shit and missfired. and now i have the problems that i have explained at the start. the fault cosde that pops up is low delivery pressure to injectors on cranking.
