My 1978 GMC 35 vandora was running when suddenly it shut off. I figured it was an ignition problem so I replace the ignition relay distributor cap rotor coil wire's ignition module. There is power going into the coil but no spark at the plugs.
What is your question?
I replaced all the ignition components except for the distributor. Why am I not getting spark
