Lift pump?

[tree98]

The lift pump your talking about is more of a priming pump. If you turn the key to the ON position without starting it, you should hear it buzzing for about a minute or a little more. If you don't hear it, that doesn't mean the pump is bad.it could be the hot wire going to the pump.If the pump is bad its possible for it take out the gear pump with it, but if it still runs ok I would assume the gear pump is ok. Take a look at the terminals on your starter, if they look corroded and green I would bet on it being the power wire to the pump. By the way, the buzzing is loud enough that you'll hear it with no problem even without lifting the hood.
