1999 Ford Explorer Repair Question
Fuel Pressure Regulator
on the fuel rail.
why are you replacing it?? not a very common issue at all.
The regulator actually is not working properly. It starts but it is a little rough on cold starts. The cranking amps of the battery is great.
how did you determine the regulator is bad?? what is the pressure key on engine off??
When the engine is off there is no pressure.
that is most likely the pump. there is a check valve in the pump that is common for failure. did you pinch off the lines to confirm??
Actually no I didnt
