Rumcajs Posted June 16, 2020 Report Share Posted June 16, 2020 This simply doesn't compute. You had it at Nissan for 3 months and they can't find the fault? Where? Its stalling cause there is no fuel available at right time or enough when needed under load cause either wrong inputs from engine sensors e.g MAP and MAF or fuel delivery is faulty, either low supply or high pressure rail issue. This should not be that hard to figure out by measuring observing engine sensors and their outputs. Or is turbo charger faulty? Example the variable geometry vanes are fully retarded cause the vacuum control is leaking. Easy to see via OBD2 scanner. Is fuel rail pressure sufficient? I mean what sort of Nissan imbecilles can't use their Consult diagnostic interface to figure this out? They should be seeing data coming during road test and relate/collate that data ffsck! I'm sorry but If I had an afternoon with their gear connected I'd tell you exactly what is wrong. You need to see what ECM sees when the stalling occurs. Fuel rail pressure, Manifold Airflow and turbo boost, EGR position, any smoke out of exhaust, even accelerator pedal position.... I suggest you visit Bosch authorized diesel fuel injection centre and have them diagnosed this on the dyno where they can simulate engine loads to pinpoint the issue.
