Well, if we're talking about a fuel injected engine then the only "switch" in the system besides the ignition switch and the ECM turning on the relay to power the pump is an oil-pressure switch screwed into the block just above the oil filter. 2-wires. Provides a ground, I beleive for the fuel pump relay. If there is no oil pressure the relay will not be grounded and the fuel pump won't run.
Please note, that even if this switch is not working you should still get a 3-4 second running of the fuel pump when you turn the key to the "on" position. If you don't, it's not this switch that's at fault.
Hope that's the switch you're talking about, you didn't give any details.
