Since I have had the mechanic look at it, he brought up that when I bought the truck it was used and it did not come with the keyless entry or the chip key ignition. I have just a regular copied key for the ignition and a black top key to open the door. The mechanic is thinking that the security program might be ingaged and shuts the fuel off at the pump. It makes sense, I have seen the security lock light come on a couple times. The Dealership was supposed to order my owners guide but said its back ordered and I am unable to look it up in the book. What do you think my options are to fix this. New ignition with a chip key.? Flash the computer. Thanks in advance.
