What would happen if I started my car in zero gravity?

If you had a fuel injected engine and an elastic fuel bladder, the engine would run, and you would probably get enough lubrication from the oil to operate short term. If the car was not strapped down or attached to anything, it would begin to rotate around the same axis, but in the opposite direction, of the fly wheel to conserve angular momentum.
