I just started my truck after it has been sitting about 2 wks and it's throwing codes P0048 (Fuel rail pressure above max limit) and P0148 (Fuel delivery error) and Invalid skim card. It also made a rattling when it first started. What exactly do these codes mean and is it ok to drive and tow my trailer?

Check all the connectors that your edge hooks into, and use some dielectric grease in them. My quadzilla caused the same fuel related issues and that fixed it. Now the skim thing, I'm not sure about. I hope this helps you.

 

Hmm, invalid Skim card. My truck did that a while back and I had to take it into the dealer.

Parts/Service fixed it right up but offhand I don't remember what he did exactly. It was related to the Key Security system though.


Parts, you remember what that was?
