Sounds like the starter. Can you hear the solenoid engaging?

If it is engaging but not turning the starter motor may be bad or it could be a bad connection or bad ground.

If it is making absolutely no sound check the voltage at the solenoid wire with it off the starter. It's a 2 person job typically unless you are creative but take a voltmeter to the wire and ground and have somebody turn the key.

If you have voltage then it may be the solenoid or starter itself.
Pop the starter out and bench test it. If it still does nothing replace the whole thing its cheap easy and a warranty is always a nice thing to have.

If it works on the bench and not in the car it is definitely connection or other electrical issue.

If you have no voltage then you may be looking the ignition switch or a broken wire.

maybe a little background would help, did it run fine yesterday but just stop starting today? Did you replace anything?

oh woops sorry about that i took my little 305tbi and dropped in a 350 carb'd motor

Can you say, "VATS"?

Sounds like he's probably on to something there, when you turn the key does the security light come on/stay on?
