I recently borrowed my fathers car and after driving it for a couple days it was starting hard and spuddering. I noticed a gas/oil trail around the gas cap, looks like 2 stroke gas was put into the tank accidently. I removed a plug and it had substantial oil build up so I replaced all plugs and wires but the car will still not start. I know that oil in the gas will not hurt the motor but the small device the allows fuel into the fuel rail is leaking small amounts of fuel. I'm not sure what to do next.

Oil in the gas can damage the O2 sensors, convertor, injectors, seals etc.

I would remove the tank, clean it out and flush the fuel system from the fuel rail back to tank.
Replace fuel filter and injector seals.
