Trane rauc 402-A New run capacitors but still not running. HELP

Not sure on the tonnage I’m pretty sure it’s a 4 ton to be clear. But have replaced 2 run capacitors to compressor and to fan as well. Came on once and fails to do so anymore. Would like to replace contacter too since no power is passing thru when calling for cooling. What type of contactor do you guys recommend, also any other possible issues?

Checked continuity on the compressor windings, checked voltage to everywhere, only seeing 230 hit the contacter and nothing coming out the other side.
