The control module is inside the distributor. Looks like this:

That is not the module i'm refering to.But, thanks for the reply! This module plugs into the distributor. I think it is under the dash or on the other side of the firewall.I just can't find it!!!

The 4.3L is behind the distributor on the air pipe.
The 5.0L is on the brake pedal bracket according to Mitchell.

The spark control module is forward of the glove box on my 85 C10. I'm swapping out SCM today.

Wake up this morning & truck would not start. Having the same problem - No Spark! WTF!!!!

Could a weak battery be causing this?????? Anyone?

Check the power and ground to the spark control module while it won't start. If you suspect a bad connection you can jump power or ground or both to the module as a test.
