i have fc 500, 622, 1693 and 1765 on my Dodge 2001 5.9l, this seems like an earth issue? it feels like fuel starvation.

 

Is it a diesel?

 

yes it is ! 5.9l

 

I didn’t plug the comp yet but you’re right that could be an earth issue and that feels like the pump Is cog wheeling, kind of. it’s like the pump deliver the fuel and then stop for few seconds and start again. It’s really annoying and frustrating!
