Hi All,
I hope someone can help me with this issue. Had a search on this and the Alfa forums but found nothing.
Had a breakdown in my JTDm 120 Multipla some months ago, the car stopped and just wouldn't start again. Changed the crank and cam sensors but nothing.
I towed it to try and start and an error of no high pressure came up so I assumed it was the HP pump.
Winter kicked in so I just got a spare car to tide me over. Have since taken off the HP pump and it seems fine, so I looked further.
To cut a long story short, the low pressure diesel lift pump from the tank only starts for a second and then turns off. It can still provide over 2.5 bar of pressure in that time but doesn't continue to pump. So maybe it was a diesel starvation issue after all.
Anyway, anyone know why the pump might want to stop pumping? It literally is for a half a second, so won't fill the diesel filter never mind bring fuel to the HP pump.
Thanks.
