Remove the distributor cap and, if you have a remote starter, follow the manufacturer's instructions to turn the engine over until the rotor is pointing towards the number 1 cylinder. If you don't have a remote starter, rotate the crankshaft until the rotor is pointing towards the number 1 plug wire terminal.
