No, lml have a regulator on the rail and one on the pump. Check the fuel rail pressure relief valve located in the front of the drivers side fuel rail. P0088 is rail pressure high, the rest of your problems sound like starvation, which usually throws p0087.

Pump one kicks in above that. Truck runs great and i just can't figure out what the deal is. There is also a regulator on the return side for return fuel that keeps pressure on injectors to stay above 60psi Truck runs great but on start up rail pressure jumps up to 60 mpa vs desired 30 mpa.
