PO088 code
Hello fellas, Yesterday my "SEL" pops and after scanning I got code PO088 (Fuel rail system pressure too high) and noticed the sensor is located at the fuel rail next to the oil cap.
My car is a 2014 E250 BT
Has anyone tackle this with replacing the sensor and fix the issue or is there more to it?
TIA

I would not start throwing parts in the engine bay until it's proven to be a persistant code problem.

Doubt that this is a possible repair but the reason that the fuel pressure would be high and the pump need replacing is that there must be a pressure regulator built into the pump. Wondering if that can be replaced / repaired on it's own.

UPDATE, after replacing the fuel pump and driving the car for a few weeks, the cars performance and MPG when down and an engine vibration. Toke it back and the Mechanic says I need a new fuel rail that will cost me another $1600 My extended warranty will cover only half that.
After the replacement of fuel rail, car still running like **** and the ENGINE LITE came on with a PO2002. (Dirty DPF)
At this point, if the car is not fixed properly, This guys is taking a trip with me to the court house soon
I miss my car

I'm with bmwpowere36m What is wrong with the fuel rail? Seems like an excuse to change another part to me. Is there a fuel rail pressure sensor? Has that been tested? Has the FRP sensor CIRCUIT been tested?

Well, bad news. The repair cost me $2,800.00 (fuel rail and fuel pump) and now the car runs very rich which damaged the DPF and O2 sensor
The mechanic told me I need to go to the dealer to have the PCM re-flashed ($400) and the car still running like crap.
Then he said that is an emission system defect and it can be replace for free as for FEDERAL EMISSION LAW.
I cant believe a got hosed by this guy. Hes going to court soon
Im so pissed
