Well, I dropped the truck off at the dealer today, i spoke with the tech, and he said to leave my spartan on there, if he thinks they will need to come out to inspect it for warranty, he will call me and have me pick up the truck and put it back to stock, He said he also thinks it will be the HPFP.

 

210 Spartan tune.

 

There is no doubt in my mind That this is the high pressure fuel pump.... same thing happened to me about 2 years ago I could turn off the truck and everything would go back to normal..... with no codes.... I took it to the dealership... and it was a cab off fuel pump replacement... oh and I have a tuner to and they did not come out and check... the tech is probly worried about it and he does not want to get in trouble... I don't blame him

 

Yes, they confirmed with me that it is the HPFP and they also said i can leave my tuner on. However its been sitting outside not yet started on. They said they should probably start on it Monday, and I may have it back Tuesday? I doubt that....

Did you have both codes as well?

 

A pump replacement can be done in a day.

 

I'm sure it can.... but the question i have is... will it be? My luck probably not!

 

Good point. If u need it done in a day it won't be. Atleast this is how it works for me.
