hi guys got a mondeo tdci brought to me with an occasional starting up issue and a p0191 stored, when starting i noticed a low idle which seems to be linked to fuel pressure as after a few seconds fuel pressure would rise slightly and than idle fine. However luckly it seems to have given up whilst i was looking at it i have a crank signal and cam signal but fuel pressure signal wont rise from the half volt you get with ignition on, i have tried disconnecting imv and injectors to see if pump will produce any pressure still nothing i have no blockages in lines and fuel in the tank and it doesnt seem to have a lift pump tank end is this enough to condemn the hp pump or am i overlooking something thanks lee
