What happens if distributor cap and rotor malfunction?
If the distributor rotor and cap malfunction, the voltage from the ignition coil won’t be redistributed to the spark plugs, and your engine will either have a hard time running, or won’t run at all. “Finding a trusted mechanic at a reasonable price can be extremely difficult.
What to do when your spark plugs don’t work?
It takes very high voltage and delivers it to fire the spark plugs. When the distributor rotor and cap are replaced, the entire ignition system should be inspected.

Why are my spark plug wires not working?
Your spark plug wires carry power from your distributor to your spark plugs. They feature a boot at each end and an insulated conductive core to carry the current. Over time, spark plug wires and boots may be damaged by heat or wear with age. If you’re not getting spark to one or more cylinders, this could point to a problem with a spark plug wire.
What happens when the distributor rotor and cap fail?
Excessive or unusual engine noises Your vehicle may make some very strange noises if the distributor rotor and cap are malfunctioning – specifically because the cylinders will try to fire but fail. You might hear a tapping, clicking, or sputtering sound when the distributor rotor and cap are failing.
How does the ignition rotor work on a distributor?
During this time, high voltage is created by the ignition coil, and sent through the coil wire to the ignition rotor. This rotor turns inside the distributor, and as it does so, it evenly distributes sparks to the spark plugs, through the spark plug wires.
How long does it take to remove a distributor rotor?
Some rotors fit freely on the distributor shaft; while others are secured with a screw. If your vehicle has a rotor secured with a screw; always use the new screw. According to most service manuals, the job of removing the distributor cap and rotor itself is only about one hour to complete.
When to replace the distributor cap and rotor?
The cap and rotor are critically important for power distribution and need to be replaced periodically. Disconnect the negative battery cable. Locate the cap, with help from the vehicle owner’s manual or a repair manual, if needed. Loosen the distributor cap.
What are the symptoms of a broken distributor cap?
Some of the common symptoms of a damaged or broken distributor cap or rotor may include the following: The Check Engine Light is illuminated: The distributor cap and rotor are vital parts of the ignition system on most older vehicles on the road today.
Can a distributor cap fail at the same time?
It’s very common for both the rotor and distributor cap to fail at the same time; especially if the rotor fails first. The engine idles rough: There are small electrodes on the bottom of the distributor cap called terminals.
Can a bad distributor cap cause an engine to stall?
A faulty distributor cap can cause your engine to stall. Voltage must be produced by the spinning distributor rotor for the engine to keep running. If the rotor does not rotate properly, the engine loses power and stalls out as you’re trying to drive.
