Was driving the truck the other day and it just died on me! Won't fire and pulled the bolt out of the fuel filter and it wouldn't spray fuel. It threw the code 252 when scanned. Any help would be appreciated! Thanks

 

P0252
Injection Pump Fuel Metering Control "A" Range/Performance (Cam/Rotor/Injector)

couldnt tell ya exactly what it was but there is the code description.

 

I don't see a fuel pressure gage. Could be the fuel pump is gone.
