The ignition module is under the distributor cap. Mark the spark plug wires location then remove the cap. Remove the 2 screws and connectors.

I have a 1993 GMC sierra 1500 extended cab 4.3 v6 TBI and I'm hearing stories about this Accel Remote Mount Super Coil burning out Ignition Control Modules

I don't know about your particular application, but I do know that manufacturers are not using heavy enough wire for many things on a vehicle. So if the coils are bigger (higher output voltage) then they probably would draw more power and more load on control modules. I don't know any reason why stock would not be enough spark, these are a lot more powerful already than ignition systems were 40+ years ago. So in my opinion, no I wouldn't do it.

Where can i find the ignition module on a 1993 saturn ?

The ignition module is mounted under the ignition coils.Just follow the ignition wires from the spark plugs to the coils.
The coils need to be removed from the module. There are two wire connectors to be removed as well.
The setup is similar on both engines available in the SL line that year.
Look at the coils carefully for burn marks from a possible errant spark discharge as this can damage your new module.Replace as necessary.

Have a 1993 gmc sierra. runs fine most of the time . but will just kill sometimes out of the blue. does not matter if it is warmed up or cold. when it dies will just turn over but not start. replaced spark...

When this truck dies,does it have spark,or fuel pressure?Check it for no spark,if it has no spark,replace the ignition module.These gm year models are bad to go out ,and the distributor pick up coil also.Replace the module first,if this does not help,replace the pick up coil.NOW ON A FUEL RELATED PROBLEMit could be fuel pump,fuel pump relay,or the pick up coil.The pick up coil pulses the injectors,and the spark.I hope this helps,if not let me know.
