What are the steps to follow when youre going to install a 1991 Toyota Camry 2.0l Distributor,

Take the screws out of distributer cap, mark exactly where the rotor is pointing with paint pen on distributer cap and distributer. Loosen bolts holding down distributer. Lift out distributer after you unplug electrical wires. Place new distributer in place making sure rotor is pointing to exact same place where the old one pointed. Replace distributer cap and electrical wires and your done, try to start the car.If car starts your ok.If it doesnt start andd backfires it means rotor is in wrong place,take back out and restab it.good luck
