5.4 engine won't start
I have a 2003 F-150 with a 5.4 engine. After installing a new gas cap and driving a few miles the truck won't start. I can take the gas cap off and the truck will start just fine. Is the gas tank vent tube clogged and if it is where can I find the vent tube? Thanks

When you take the gas cap off after driving it, does it hiss with a lot of pressure? If it does then your vent is clogged, and it comes off the top off the tank and usually runs into a hole in the frame so the hose dosen't drag on the ground.
