Michael, good thought but unfortunatly his brother tried to start it apparently. The only thought I have is to lock the pump with the built in device. Make sure the valves are both lobes up and balancer pulley is at whatever recomended static timing position and slide the pump in. Pump indicator slot is probably start of delivery for the first element on that pump. Someone else will clarify that. I do not own one of those pumps and have never timed one. All required information will be in service literature. Not really a true disaster. Far worse can and will happen with brothers. I remember when one identical twin brother was taking out his brothers girlfriend without telling her or him. Not only was it a real timing problem but a war errupted over it between them. They were and are still identical in apperance.
