I bought a new breaker, but that wasn't the problem. The pump is turned off, but it still is tripping breaker instantly. It's attached to an Omni control system so I wouldn't think any power is even going to the pump. I'm also having a problem with a fairly new LED pool light that is dim, but again no power to it now, it doesn't trip breaker either so I don't think it's related problem. Even if there were water in the pump somehow it shouldn't trip the breaker until I turn it on, should it?? Has me befuddled. Pump does stall sometimes if I turn it off, but that seems to be a known Hayward issue and it comes on eventually. Anyone have any ideas. I'm not even sure a new pump would solve the problem since even when breaker is on, I don't think controller is sending power since it's off?

Is your pool pump breaker GFCI?
What model LED pool light and transformer did you install?
www.troublefreepool.com
False GFCI trips can be caused by a low-voltage transformer turning the light(s) OFF or ON/OFF either via light switch or relay, even on an unrelated circuit.
The inductive kick of an isolation transformer causes a brief arc across the switch contacts, injecting arc noise into the supply wiring. This brief noise feeds back to the panel and all the installed breakers. The circuitry inside the GFCI breaker may react to the arc noise and trip, even though no ground fault current is present.
A snubber capacitor (arc suppressor) across the transformer's primary leads (line to neutral) on the load side of the light switch or relay can prevent the arc noise and GFCI trip.

It is a intermatic 300, but I completely cut off the power to it (both leads
I completely disconnected lights blue hot, white at transformer since I couldn't be sure which one, and even ground at transformer. Certainly seemed logical since I was also having dim flickering problem with light, but even with transformer completely disconnected breaker trips immediately

I just tried turning off power to entire Omni since the power for it goes through the light relay so only pump breaker would be connected and it still trips

Your pump is wired directly to the breaker as a VS pump should be.
As soon as you turn on the breaker you are powering the pump controls. Even if the pump motor is not running.
To be clear, are you saying that as soon as you turn on the 20A GFCI CB for the pump it trips off?
There is a difference between the VS pump control being on and the pump motor being on.
The OmniPL only controls the pump motor. If the pump CB is on, the pump controls are always on.
It is difficult seeing all the wiring around your pump CB from the angle of the picture you posted.
If you want to post more pictures of the panel and your pump showing the wiring, I will see if I spot anything wrong.
Right now it is pointing to your pump being the problem.
Yes, it is tripping immediately. I'm sure it was wired properly. If the breaker is sending power to the pump regardless of being off, I'm sure that's the problem. Do I need to replace the pump, or is it repairable

Start by disconnecting the power wires into the pump and safe them off with wire nuts.
Turn on the breaker and see if the CB trips.
If the CB does not trip it confirms the problem is in the pump.
Check the pump drive for signs of water in it.
Check the pump motor for signs of corrosion.
Separate the motor from the volute and check the condition.
If the problem is in the drive or motor, it is probably not repairable. You can check the cost of replacement parts.
