How to Troubleshoot a 1998 Chevy Truck's Distributor

Save

The distributor of your 1998 Chevy truck directs the initial high voltage spark into different plugs that ignite the truck's ignition system, thus initiating the combustion of fuel to power the engine. A faulty distributor will result in the high voltage spark being directed incorrectly or not being directed at all. If this occurs, you will need to replace your distributor in order to continue operating your vehicle. You will need a long metal object to test the spark such as a screwdriver or a long nail.

Things You'll Need

  • Long metal object
  • Lift open the Chevy vehicle's hood. Remove one of the coils from the spark plug.

  • Insert the long metal object into the end of the coil.

  • Ground the object by connecting it with some wire to a metal part of the vehicle. It would be safest to use the battery's ground-terminal.

  • Crank the engine to test for a spark. If it does not start, you may have a faulty distributor.

  • Spray a tiny amount of aerosol starting fluid into the vehicle's throttle. Crank the engine again. If the vehicle starts, then there is an issue with fuel-system. If it does not, then the problem is definitely related to the distributor.

Tips & Warnings

  • The aerosol starting fluid is very flammable. Be very careful when spraying it.
