08 F250 6.4 wont start hot -cold runs fair
Low mileage F250 . Got a check engine light then wrench light then BOTH went away and ran ok. Came back on yesterday on 65 mile trip home. Had to make one stop, 30 minutes later came back to truck tried to start...crank...no start---wanted to but didnt. Towed it home on flatbed. This morning after sitting overnight, started fine, but check engine light (no wrench), drove to work, buddy had OBD2 generic scanner, said two codes both fuel rail pressures low. Then with it hot, no start again. Its gonna go to the dealer I guess. I dont mind paying them, but last time they had it for a oil change and fuel filter change and tire rotation they put a HUGE dent in the hood from raising it on the lift with hood open and hood hit lift beam, I had it paintless dent repaired but still made me mad so now I try to avoid dealer. Any thoughts? Is this a common problem? I have always driven GMC's.

This may have been the code:
P0087 X X Fuel Rail/System
Pressure - Too Low
This error will be set if the fuel pressure in the rail is too
low and the controller cannot regulate it to the setpoint.
20 % “overposition” of the
PCV or VCV [% PWM]
5% deviation of the fuel rail pressure
to the fuel rail pressure setpoint.
Low pressure system, wiring to
VCV and PCV, FUP sensor, pump
