I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

Are you getting any codes coming up on this? All harnesses are plugged in? Did you check the return check valve to make sure nothing was caught in the head and is now holding that valve open to keep the pressure in the head when you are idling the truck?

one code. Sid230. Idle validation switch fm12 data erratic, intermittent or incorrect.
Expert:  Jeremy replied 2 months ago.

The idle validation switch is the accelerator pedal switch. That explains why it is dying out.

Replace the pedal switch. There is dirt in it or the contacts are just worn and causing the code. I see that a lot!

But will that not let it start on its own
Expert:  Jeremy replied 2 months ago.

Not always. When the engine can't see that idle validation switch, it is essentially telling the engine that the pedal has been removed. That idle validation holds your ground for the neutral switch in it as well. They run the same circuit at the ground.
