This morning I started my truck and it ran just fine for a few minutes and shut off. Then I tried to start it again and it would run a little bit and shut off. I was told to try the fuel filter so I changed that and still have the same problem. What should I check. The truck won't pull up any codes on my diagnostic scanner.

Welcome to the forum, do you think the security system might be causing an issue? Use a gage and check fuel pressure. Some of the national brand autostores used to loan a fuel pressure gage. You can call and ask. The fuel poppets are known to stick, if you have the spider fuel system. The cleaning procedure in the service bulletin, is a shop procedure. Right now, I'm not sure what is causing the problem?
