You are in a position to start the engine if all the all bodywork, braking system and steering have been checked. You'll also need to check the tyres and exhaust system and the condition of the battery. And think about how old the fuel in the tank is. If you're unsure, drain and refill it with fresh fuel.

First, remove the plugs and put a small amount of engine oil into each cylinder and turn the engine over by hand a few cycles so making sure that the cylinders are not too dry. Then carry out a complete check (or replacement) of the ignition system. Remove and test the Injectors (if not done on the rebuild) and drain and replace the engine oil plus filters. Replace the fuel filter and also check and replace the air filter if necessary. Next check or replace any coolant hoses and change the brake/clutch fluid. It's wise to change any drive belts as required and carry out a pressure test on the cooling system .
There may be other areas that we have not covered, so you may want to contact the Porsche owners club, as we are sure they will have more detailed information. Hopefully the Porsche will be back on the road soon.
