Lately I have had an idea for a propulsion system. It would use rapid high voltage electrical discharges to create thrust. Now if it was strong enough and made correctly could this be an efficient form of thrust? Would it work?

You want to shoot lightning out of the back of a vehicle in an attempt to produce thrust?
Efficient in this sense means getting as much movement per unit of energy as possible. The amount of energy required to produce a bolt of lightning is 'a tad high' and would produce no motion of the vehicle - extremely inefficient.
