Unfortunately you have already damaged the motor running the engine until it dies when it lost oil pressure. The bearings for the crankshaft and camshaft have been starved of oil and seized the engine. You will need to have the engine first checked to see if you can turn the engine using a socket on the front crank pulley bolt. If you cannot turn the motor then you have a seized motor. If not then the starter circuit needs checked.
