Default fuel pump question

Ok I needed to find out what was going on with my fuel pump so I went out and spent $20 on a voltmeter tester. I'm sure a lot of you have seen the connection that goes to the fuel pump above the gas tankwhich is a smallcircular plug consisting of four prongs that plug into the same size socket plug. So I tested two of the plugs opposite from eachotherforvoltage and they gave a steady reading of around12 volts.

Shouldn't I be able to test somewhere for some kind of voltage jump as the car tries to turn the fuel pump on or am I supposed to get a steady reading like that?

Sounds like your fuel pump relay is stuck... I believe its under your driver's seat and you can test it with the same volt meter you just bought. Just set it to Ohms and check the continuity of the circuit.

How exactly do I get it unstuck?

You guys all think I should just replace it and see if that works?
