Have an interesting problem with my 03. When it it less than 30deg and I'm unable to plug the truck in at a customers site the truck will start and then immediatly quit. The first time this happened I got out the screwdriver to bleed the fuel system and decided to just press the primer button on the fuel filter until it got hard to press. When I do this the truck fires up and stays running just fine. This only occurs if the truck is not warm. Is this a sign of poor fuel pressure? Is this a warning that the pump in the tank is getting weak? Any help is appreciated!
 
It's usually an indication of a fuel line leak.
Start off by checking the fuel filter seals (3)...I would just change the filter.

Also, there is no pump in the tank. It's bolted to the engine (CP3). It sucks the fuel from the tank through the filter. You will not see a fuel leak because most of the sysytem is under a vacuum.
 
check the bleeder screw too. if you've tightened it up too tight it'll be stripped out and bleed air in.

Mine does the same thing, the moron at the dealer didnt put the filter back on correctly so it is losing prime.
