How do I adjust my flash mode on auto shooting mode?

Yes, just put the camera in manual mode with shutter speed within x-sync range. Select the aperture based on either the auto flash or guide number (manual flash). The flash can provide auto exposure but excess ambient light will not cause any exposure adjustment by the camera, so just be aware if shooting flash involves going out into daylight, etc.

When you wait to long to shoot it thinks you have left it
You will ha e to reset it.

if u select mannual mode u have to press flash button,whitch is on left side below flash unit,if u select auto mode, flash itself elect when u half press the click button.

Double-check your flash settings. You mentioned the camera is in Auto mode, but the flash has separate settings from the camera's shooting mode. With the camera in shooting mode AUTO check the Flash settings (Auto, Red-Eye Reduction, Fill-In, Off) It may be set to 'fill' causing your photos to be too bright.

Also, depending on how close you are to your subject the flash may not be needed. Using the flash when too close to your subject (less then 3 ft.) will cause bright/white photos. Turn the flash OFF if you are taking macro or photos closer then 3ft.

If neither of these fix your problem, turn the flash mode OFF, and camera shooting mode to AUTO and in a naturally well lit area, take a photo, if the photo is still too bright, you may have something mechanically wrong with your camera.

A few suggestions for outdoor flash too bright with SB-600.
1 - If flash is in the auto mode, try hitting the (-) symbol a few times to lower the flash output
2 - Quick fix for close shooting - pull down the diffuser. You loose about 2 stops of flash light and effect is much softer. Don't forget to raise it later or you might think you have the opposite problem
3 - On the camera side, you play with your ISO. Depending on the scene, changing ISO can increase or decrease effect of flash vs background. This can be tricky to predict in auto because the camera is doing calculations of its own.
4 - You can put the camera in aperture mode and set your apeture so that you get a good balance between flash and ambient light. The camera will adjust the shutter speed, which increases or decreases the effect of the background - while the flash remains a constant. This can be very effective in tricky lighting situations, but be prepared to take lots of test shots to get it right.
5 - You can put the flash in manual mode. That will give you a consistant fixed reduced flash output regardless of what the camera tries to change. You have to keep checking your display to see the effect, but with camera in auto this can be a winner.
6 - Finally, you can go "old school" and put both camera and flash in manual and find your best combination. When I'm pressed for time in tricky conditions I often do this by finding a good setiting for a fixed distance, and then adjusting my apeture up or down as I shoot closer or farther things. We had to do it like this back in the day, and with the histogram on the display, I can get dead on where the camera "brain" would get tricked.

My flash doesnt work either. Holding the flash button down doesnt do anything either (in program mode)
