I tried to start my 66-300 440 TNT engine. The engine has not been run in six months. Never had a problem with it starting before.
About 3 months ago , I put a Genius 2 battery tender on it. The battery shows to be fully charged with 13.5 Volts. I checked the oil
before trying to start it, dip stick shows full. I turned the key to start, the red oil pressure light came on, totally quiet, not a sound from
anything in the engine bay.

I would appreciate all suggestions on finding what the problem might be and then how to fix it,

Try moving the gear shift lever thru the gear positions ending in neutral, again attempt to start. If no start, Remove and clean the battery cables and try to start. If you still have nothing, Mopars are famous for having the starter relay stick from sitting, rap the relay with the handle of a screwdriver and see if that helps, be sure the terminals to the relay are clean, they are also famous for corroding.

remove and clean the ground cable where it attaches to the head/intake/block.

I like to short across the relay first. If it cranks it eliminates the battery,starter and starter connections without taking anything apart.
From there you can put yor test light on the relay to confirm it is recieving voltage when the key is turned to start position. With this process you can nail down what portion of the system the fault is in within one minute.

Do you have full battery power at the power input for the starter relay?
Do you have voltage from ignition wire connector at starter relay when key is turned to start position?
Do you have full battery power voltage at the starter relay output wire to starter with the key in start position?
