To test the ignition control module on a 1987 GMC Suburban, first, ensure the ignition is off and disconnect the battery. Then, remove the ignition control module from the distributor. You can use a multimeter to check the resistance of the primary and secondary windings, comparing the readings to the manufacturer's specifications. Alternatively, you can take the module to an auto parts store that offers free testing services for ignition modules.
You might try a crankshaft position sensor first. Its probably cheaper than an ignition module.

No, the ESC (Electronic Spark Control) module and the ICM (Ignition Control Module) are not the same on a 1994 GMC Suburban with a 5.7L engine. The ESC module is responsible for controlling ignition timing to optimize engine performance and reduce emissions, while the ICM is involved in managing the ignition system's operation, including the firing of the spark plugs. Although both modules work together in the ignition system, they serve distinct functions.
