1995 Mitsubishi Eclipse The only thing working is the light

Ok so I'm driving and my oil filter comes loose. I replace it and fill the engine with oil. I start the car and wate a minute and press the rev the engine from under the hood and nothings wrong so I get in the car and rev it with the pedel and the car dies. What's weird is now nothing works but the lights. Now my alternater is covers with oil and I need to know what would cause this to happen.
