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.

    If you hear the pump running, fuel pressure needs to be checked.

    I understand that but that is the next step in the diagnosis! Somehow, that has got to be done!!
