Sounds like the pump may be failing. Does it run ok? have you reset the code and did it come back?

It wouldn't start so I got my Superchip Flashpaq and plugged it in and it gave me that code. Maybe 5-10 minutes later I tried it again and it started. Drove it home from the north woods, about 150 miles, 2.5 hours, shut her down and 5 minutes or so tried to start it and it fired right up.

EDIT: Trucks been sitting for 30-45 minutes now while I updated my 3815. Went out and plugged it in after the updates and I cleared the code. When it was done the truck started right up. We'll see what happens in the morning.

Well after $54.91 the dealer says

"Diag inspect wire resistence and wire connections all good. Stored code can be because of a long crank time. Overfilling fuel can cause this"
