an electronic spark module basically takes the place of set of advance weights and vacumn advance. it reads input from different sensors and engine conditions and either pull time or advances it for load, speed, throttle position etc... an electronic spark module basically takes the place of set of advance weights and vacumn advance. it reads input from different sensors and engine conditions and either pull time or advances it for load, speed, throttle position etc...
I believe in 93 they had the newer style computer, this eliminated the electronic spark control module.
The ESC module is in the distributor
in the distributor cap
Right next to the gas moduale
Yes.
It advances and retards the engine timing as needed.
its inside the distributor.
Generally if the spark control module on an engine is bad, the car will run roughly. It will likely miss and die at low idle speeds.
Inside the distributor, under the rotor.

ESC stands for Electronic Spark Control it may also stand for Electronic Stability Control. The Electronic Spark Control module will retard the timing if it detects any spark knock or pinging or even other similar sounds made by the engine such as lifter knock.
The ignition control module on a 2000 Blazer with the 4.3 is mounted on the same bracket that the coil is mounted to.
