Weak spark 1987 honda civic si
 

My car shut off on the interstate and hasnt started since. My fuel pump is priming and im getting gas to the injector.
checked for spark from spark plug wires and spark was weak.
Replaced distributor cap and distributor rotor, spark plugs and wires and ignition coil. Spark is still weak but better. What steps should i take next?

Check and clean all engine and chassis grounds.
Did you use a Honda Genuine coil? Test the igniter?
Did you use NGK spark plugs?

Watch the spark test video in my signature. It's for a 6th gen but should work for your car's engine. Have you verified mechanical timing and compression? Are the cylinders flooded with fuel?
