The opening and closing of the points, once for each cylinder for each rotation of the rotor, helps create the high energy spark from the ignition coil. If your vehicle has over 60,000 miles on it and you haven’t replaced your spark plug wires, distributor cap and rotor, you may experience a variety of drivability problems that are often difficult and very costly to diagnose and repair. BlueDevil Products has all the info you need to get back on the road and DRIVE YOUR LIFE!

When you put a new cap and rotor on, the position of the rotor isn’t an issue, it only fits in one position. But a lot of white smoke was coming out, which is what it was doing before this happened. This causes the ignition module and coil to produce even more voltage, creating even higher current temperatures within them. It's not clear to me though why this would prevent the car from starting. Step 4 – Install the Distributor Cap. Brass cap contacts conduct better and last longer. As the rotor passes under each terminal, electricity travels through the cap, and out into a Thank you all very much. 3.
