The 1.1 amp readings for a no load pump would be what I'd expect.

The 5 amp unit is probably pushing through gummy fuel and the other one locked solid.

Just to be sure of the hookup, the meter is set to amps, positive test lead on meter side moved to "amps " socket, one wire lifted from pump, one meter lead hooked to pump, other to the wire you just removed. For a digital meter, polarity does not matter, you may get a negative reading. For an analog meter , if the the needle drops below zero, reverse the test leads.
