The fuel pumps will only run for one second each time you turn on the key.
Are you saying that the selected fuel pump will not run for the one second?
Do you have two fuel tanks? If so are you saying neither fuel pump will run for one second?

Bad fuel pump? Maybe, but could be other items as well.

What year is your truck?
What size engine do you have?

1990 f150 302 shortbed, so I only have one tank and I can't hear fuel pump turn on for the 2 seconds. When u try to start it all it does is keep cranking over and rpms might reach 200 but won't start

Check your Inertia switch by pushing the button down on top of it.

No luck, ground pin #6 of the self-test plug and turn on the key, does the pump run all the time now?
