You can check for power at the starter itself while cranking the engine over, there are two wires, one is a big wire that will be "hot" at all times. This powers the starter motor. The other smaller wire comes from the ignition switch. This wire will only have power while cranking the vehicle over (twelve volts- battery power). This is the starter solenoid wire.
Usually a bad starter will just click, but battery problems can cause this also. So you want to make sure you are getting a full twelve volts down to the starter on both wires. You can use a automotive test light for this. They are very cheap. You will need a helper to turn over the engine while checking the starter. If full power is there, then you can go ahead with the change out, but if its not. Then you may have a relay, wiring, or battery issue.
