Mid-East Nebraska | This is a later 9750STS, because you cleaned the filter at the bottom of the fuel tank, the early takes it fuel from the top and has a tube that goes down from the top. So it will have the fuel rail system. Yes like somebody said it could be a check valve, but it should have a code about the high pressure rail sensor with low pressure at that rpms. Did you go into the system to get the codes that are there. There is a solution number 62546 about a zener diode not working and 70468 is the fuel filter inlet check valve that somebody said to but a gauge on. | |
