What does the relay behind the glove box have to do with the fuel system and where is it exactly. What does it look like. How do I check a relay. It keeps saying my question is too short so add whatever else I need to do to get my truck running. I am missing out on a lot of fun without my ride!

The fuel pump relay if it's a 2.5L is on the right fender panel. If it 'sa 2.8l it's on the left front inner panel behind a/c relay. To test it just replace ti with the a/c relay one. The relay sends power to fuel pump on initial start up so it will have pressure.
