Have tested fuel pressure by releasing pressure and then turning ignition key to position II. Although pump runs very briefly fuel does squirt out of rail valve when released.
Re-pressured using ign key and left 20 mins. Nothing, no fuel/pressure. Have found RPM sensor and taken out, it looked pretty good but cleaned carefully anyway. Found coolant temperature sensor, covered in coolant crud. Disconnected and reconnected connections for above too. Tried spare fuel pump from my old SE and that runs for several seconds when plugged in. SO, from other posts need to look at check valve or replace fuel feed unit. Is my old fuel feed unit from scrapped 1997 V70 SE 2.5 the same part numbr as for my 1999 V70 2.3T5 ? Thanks. David
