Bear -
There are two parts to the pump - the motor, and the impeller. Take a look at the second and third pix in the first post in this thread

In the second pic, you can see that when you take the plastic hood off the toilet, the motor is standing up in the middle - that's the black cylinder with the red and white wires coming out of it. In the third pic, the motor has been lifted out of its housing and is just lying there on the seat. At this point, the motor should run smoothly if you push the switch. If it doesn't run at first push, pull the rubber boot off the upper half of the motor so you can measure voltage right where the red and white wires are attached to the motor terminals. If there is voltage at the motor terminals and yet it does not run, then the motor is bad.
If it runs when it is just lying there, but won't run when you put it back in its housing, then the impeller (which is down below in the tank) is bound up. This is what Harvey is describing. If this is the case, you might be able to insert a screwdriver into the lower half of that black housing, where the motor shaft normally goes, and give it a turn. If the bind is just dried TP or whatever, you might be able to break it loose. And if you can't break it loose, you're going to have to remove the toilet, disassemble it, and remove the impeller to see what is going on.
Check those voltages really carefully. Much less hassle than disassembling the toilet.
