Hello, welcome and thanks for asking your question. My name is*****'m a Certified Auto Technician with 29+ years experience. I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

Now since you know there is no spark to the plugs, you can remove the coil wire from the center of the distributor and place the cable 1/4" from a good ground on the engine block and have someone crank it so you can check for spark from the coil, If you get spark from the coil then you need to check the distributor cap and rotor. If you still get no spark you will need to check the coil itself..

This is of course if there are no codes stored in the PCM..

Keep me posted...

Thank you,

Robert
