Access the compressor common, start, run terminals. Disconnect the wires from them and test them with an ohm meter. You should have a measurable resistance between each terminal and infinite from any of the terminals to the compressor case. If that is good you want to check if you have a starting relay if the relay is bad the compressor will have very high amps and then go off on either the thermal overload of circuit breaker.

Bad capacitor or low pressure switch or maybe safety switch on condesate pump or ptrap

Check if you are getting 24 volts to you contactor coil on your condensing unit. If you are that means your problem is in your condensing unit check voltage going to your condensing unit it will be usually 208 to 230 v.

No special tricks alyson.....prolly just a breaker or fuse.check the main panel for a turned off breaker and at the unit there's a disconnect box that may have a bad fuse.
