Where is the electronic spark control on a 1994 suburban 5.7 located at?

Answer 1

If I understand correctly, the Ignition Control Module is located inside of the distributor. To replace it remove the distributor cap, which is locted in the center rear of the engine compartment. If there is adequate room, leave the spark plug and coil wires attached. Set the cap aside and look for a wiring harnes on the bottom of the distributor. I should be attached to a small flat black module that has two small bolts holding it in place. Carefully remove the small bolts, and unplug the harness and remove the Ignition Control Module. Replace and assemble in reverse order. Make sure to get the distributor cap on the same way and do not rotate the distributor during the process.
