Almost Stranded by my 2016 Platinum

Who scanned it? Dealer or auto parts store?

I did with my FORscan. Error code was P008B. After some research points that bad gas could cause said issue.

I'm curious about your source of info. Everything I've read on it indicates high fuel pressure in a low pressure fuel system.

Wow Alaska, that's far. I have distant relatives in Fairbanks. Do you think that the thud could have been anything from the road? I.e. a rock, a big stick, a moose.... (Alaska, right?) Did you look under the body and see if there was any kind of dents or damage on the driveshaft, axles, transmission, etc.? Of course, it could just be some bad gas. Just trying to see if there are any other factors.

One of the things that can cause that is bad fuel, on several sources I read.

Not implying either you or the source is incorrect, I'd like to know how "bad" gasoline can cause such an increase in pressure that a code is issued. If the gasoline is thicker you would have an increase but aged gas, I doubt it. Mixed with water, runs like crap but I doubt the viscosity change is enough for a code.

That code is usually used on the diesel side of things. Fuel purity is paramount to a diesel running correctly. The fuel filters are designed to catch the impurities so that the injection pump isn't destroyed due to extremely close tolerances.

So one thing to check is if diesel is in the tank, it is higher viscosity than gasoline by a little. And the fuel filter should be changed with a name branded filter.

If I remember correctly there isn't a test port on the fuel rail so you would need to add one temporarily to take a pressure reading. Read the pressure and see how high it is.

Swap the sensor first. Thats the most likely issue.

I appreciate all the information! It's running great now after I added some HEAT to the tank.. so I have been in contact with the dealer and they said to try that and if my next fill up it has issue to let them know. They aren't opposed to shipping it down there if needed.

Zack, How far away from the dealership are you?

I live on an island so it's about a $1000 barge ride.

shiiiiiiiittt
i see why you are trying to fix it at home
