Default Corvette C4 Problem with MAF Erratically engine

After buying a Corvette, I replaced the spark plug and the stepper motor. I replaced the fuel with a new one.
The Corvette had an uneven engine speed after firing. I managed to ride it for about 500 meters.

When trying to start the engine again, the Corvette won't start.
I cleaned the MAF, checked the air filter (it's clean), changed the fuel filter.
Corvette won't start.
After unfastening the MAF, the Corvette fires, but it works unevenly and can not enter the higher revs.

Below are the videos:
