It's likely under the board. Forget about that until you get the supply running.

Pin 4 is being driven high which is shutting the IC down. When you get a chance, I need the same for the LM339.

The information that I have that should be for this amp doesn't match your 339 numbers.
Is there a Q703 that has its emitter connected to pin 14 of the 494 and its collector connected to pin 4 of the 494?

A: You are 100% correct.
I rechecked 339 and I made a mistake on pin 11 it's 0.

The diagram I'm working from has only inverting inputs connected together, It appears that 7 and 8 on your 339 are connected together. Do you read 0 ohms between them?
Lift that transistor and power up the amp. The amp will likely power up without remote so start watching it as soon as you connect B+. This will disable all protection so, if you have a current limiter, use it.
It would be better to do this with all FETs clamped tightly to the heatsink until you see what the amp does when you power it up.

I changed the 339 and turned it on and got a flash of red then solid blue but no sound then 1 minute later the sound starts working.
Sometime when I run the amp it works straight from the start. No matter how the volume level is the blue led is on then it cuts the sound off and 30 to 60 minutes it cuts back on for 2 to 3 minutes and repeats. But after a while of the it just turns of the sound until I restart it.

You should get the voltages on the 339 when it's working and compare to when it won't power up. That may help to narrow down the problem.
Are you using the jumpers like those used for JL amps or are you soldering individual wires?
Does the preamp board have to be in the circuit for the amp to power up?

Sorry it took so long, it would not start up last night.
I left on today and in about 2 hour it just turned on and started doing the loop thing.

A: I used Arduino like jumpers.
Q: Does the preamp board have to be in the circuit for the amp to power up?
A: I don't think it does but the audio input is on the card and I don't want to sit there for 30 to watch it cut on so I go about my business until i hear it.

When sound is not working the blue led is still on and the amps from the main power is at 0.020.

I don't think the 339 is involved. All of the outputs are the same as they were when you posted the other voltages.
The jumpers you used are better than making individual jumpers but the type recommended for the JL amps require no soldering. They are item #14 on the TT5 page if you missed them.
I think you'll have to lift the transistor and repeatedly power cycle to see if anything every fails to work properly. That may indicate whether the problem is with the audio circuit or with the protection circuit.
