3:45 PM PT -- TMZ Sports has obtained video of Enzo after he was forced to leave the plane.

Ex-WWE star Enzo Amore was kicked off a Delta airlines flight Thursday afternoon ... after taking a hit of a vape pen on the airplane.

Amore was on a Delta flight -- scheduled to fly from JFK to LAX -- but the plane never got off the ground with him.

Our law enforcement sources tell us Port Authority police were called to the aircraft ... but did not arrest the wrestling star.

We're told Delta refused to put Amore on another one of their planes ... so he had to find another way to travel to Los Angeles.

A rep for Delta tells us ... “A customer was removed from Delta flight 747 operating from New York to Los Angeles for not following crew instructions."

"The flight returned to the gate at John F. Kennedy International Airport where the customer deplaned without further incident."

FYI -- Amore was once one of the biggest stars in the WWE ... but was fired in January 2018 amid rape allegations. Enzo was never charged in connection to the alleged incident.
