everyone I have talked to says there is a Electronic Spark Control Module on my 1993 GMC Suburban. some people say its by the throttle body, others say its on top of the heated core behind the glove box. I cannot find it anywhere. I have the 350 w/ coil, distributor, ignition control module inside the distributor. any advice?

The ignition module #14 is inside the distributor. The ESC (Electronic Spark Control Module) is mounted on the intake next to the throttle body(#8- Knock Sensor Controller). Here is a diagram to help you see (below) Please let us know if you need anything else to get the problem fixed.
