What causes a distributor not to fire?

This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap. Sometimes, misfiring may not be caused by a total loss of spark but by incorrect sparking or by high-voltage electrical leaks.

What causes a distributor not to spark?

Loose, broken, or corroded wires in the ignition module can be a reason behind no spark from distributor. Cleaning oxidized terminals and replacing broken wires is a good decision.

How do you check a coil from distributor to spark?

Pull the coil wire from the distributor and hold it near a ground. Again, have your assistant crank the engine and look for spark from the coil lead. If you have spark, you likely have a problem with your distributor rotor or cap, so you may want to replace them.

How do you troubleshoot a distributor?

How to Tell If You Have a Faulty Distributor

  1. Check the Distributer Cap. Often the distributor cap is suspect.
  2. Check the Contact Points. Inspect the condenser; the engine will not function if it is broken.
  3. Check the Arc.
  4. Tools and Materials.
  5. Crank the Engine.
  6. Remove the Old Distributor.
  7. Set the Point Gap.
  8. Set the Distributor.

What sends power to the distributor?

The distributor contains, among other parts, a rotor that spins, and a number of contacts mounted to the distributor cap. Power from the ignition coil is supplied to the rotor. The rotor spins in time with the engine. When the end of the rotor is near one of the contacts, electricity arcs to the contact.

How do you know if you have a bad distributor point?

Take a look at the contact points. If points are bad, the engine could experience multiple problems. Bad point connections cause engine overrun, timing issues, speed missing and causes the engine to misfire or fail to start. Look closely at the surface of contact points.
