There is not one!
Fuel pressure pump, gets fuel to fuel injector pump, which pump do you want to check and symptoms?
in injector pump
Yes the pump feeds them or you could just unplug injector(s)
The fuel injector pressure regulator is located in the injector fuel pump. Most pressure regulators cannot be separated from the fuel injector pump.
transfers fuel to injector pump from tank
there is a fuel pump under the driver side door on the frame.
injector is bad
No it is not a fuel pump problem. It either has a grounded are open circurt. Check wiring to injector. May just be a bad INJECTOR.
you open all the injector lines at the injectors . Then pump the fuel pump primer on the fuel pump . fuel will flow out one or more of the injector line , close the injector line and roll the engine over until the next injector start to flow fuel and so on , why are you having problems
Powerstroke engines that display this will have bad injector o-ring seals. These engines can also put the oil back into the fuel system. Other diesels that have this problem will usually have an injector leaking down and/or a mechanical transfer pump that has a blown seal. Injector jumper line leakage. (powerstroke57) This is a rare mix for the 7.3L powerstroke. Typically we have Fuel in the coolant, or oil in the coolant. As for fuel in the oil assuming it is the 7.3L I would have to say yes it could be injector o'rings. It's the only thing in the entire engine if failed would do this mix. This is because the injector has oil and fuel in them and those fluids are seperated by the o'rings. This would be my starting point to look their. Good luck hope this helps.
Under the car, between the fuel pump and the injector pump.
There is no need to bleed air from a fuel pump.
