Q: Fuel safety switch won't stay depressed on its own, or start while holding it on 2004 Ford Explorer Sport Trac

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Never had any fuel issues until now.
Ran fine yesterday, but no love this morning.
Cranks but won't fire. Safety switch won't click in.

Yeah. That is what I'm trying to figure out. Just hoping to find out its something small, and not a total fuel pump replacement
Check for battery voltage at that switch, if present, pump is the next likely suspect.
Pump seems to be making a little noise, when I turn the key on. But its more of a weak squeak. Thanks for your prompt response, Pushrod. Going to check voltage now.
I understand that but that is the next step in the diagnosis! Somehow, that has got to be done!!
