[MWiacek]

I started my truck went into high idle and after 10 min. It reved up and sounded rough bullydog says there is no codes but the ceck engine light is on and the rail pressure gauge is reading zero no rail pressure, truck starts fine but has a knock when it runs thanks matt

Check the plug connections at the rail for the guage. The truck would not run at 0 psi. A loose electrical connection will throuhg a code and put you in limp mode.
