Because these are most likely made in China (look at the label on the machine to see), they are "when it breaks, throw it away".
My only success has been to type the name of the company into the computer, and then call the phone number, and ask the company. Occasionally I can order a new one, usually my effort has failed.
We use these at my house, and I have had the same problem several times.
God bless your efforts.

I am assuming you have a DLC-8S Pro Custom 11, and not another Cuisinart food processor.

Remove the work bowl and all other parts completely from base.
Plug the base in, and turn it on.
Use a pen to press in the dark grey or black button on top of the base.
If you hear a spinning or other noise, the motor is still good.

Now that you have verified that the motor is good:
Put each work bowl piece on one at a time - if you don't out it on one at a time, it will not lock in properly.
Put work bowl on with work bowl handle facing front, make sure bowl locks.
Put lid on with hollow feed tube facing the back of the food processor.
Put pusher sleeve into lid's feed tube, with sliding lock switch facing the front of the food processor.

You should now be good to go.

Put the work bowl, lid, and pusher on one piece at a time - handle of work bowl faces the front of the food processor, hollow feed tube faces the back, and the sliding lock switch on pusher sleeve faces the front. Should turn on.

If it doesn't, test the motor - remove the work bowl and other parts completely. Plug the base in and turn it on, and use a pen to push in the dark grey or black button on top of the base - if it spins, the motor is still good - you may just need a replacement part. If it doesn't make a sound, it needs to be sent in to Cuisinart for repair.

Place the gearbox on top of the blender/food processor
Place the work bowl over the spindle, with the handle facing the front of the machine - make sure the tabs lock into place.
Place the stem adapter on top of the spindle, then the blade.
Place the lid on top of the bowl, with the feed tube facing the back of the food processor. Then the pusher into the feed tube.

Cuisinart Food Processors – Motor Test

First, do a motor test by removing the work bowl completely and using a pen to press in the grey button on top of the base (with the food processor turned on of course), toward the back. If the processor spins, the motor is still good. At that point, I would inspect the work bowl pieces, lid, pusher assembly, etc for cracks/damage. If all appears well, insert ALL the pieces back into place and try again. If even one piece is out of place, the processor will not spin.

If it no longer spins, the motor has a problem.

Good luck!
