My 94 blazer 4.3l won't start. IV replaced coil rotor plugs wires and distributor cap. I've got power going to the coil but still no spark from the coil. Could I possibly need a ignition control module? Any help would be great I'm stumped.

 

My son had a 95 S-10 with the 4.3 for a very short while and it went through 3 distributors. Don't really know why. He got rid of it real quick.

 

Probably the pickup coil in the distributor, real piece of work to replace.
