It depends on which module you are talking about. But yes, I've had them test good cool and bad hot.
take it off and take it to autozone they will check/test it for free
yes, but only after the cookies have been baked and cooled off.
To check the headlight module on a Mercury Capri, first, ensure the vehicle is turned off and the battery is disconnected for safety. Inspect the module for any visible signs of damage, such as corrosion or burnt connections. You can then use a multimeter to test for continuity and voltage at the module's pins when the headlights are activated. If the module fails to show proper readings or you notice persistent issues with the headlights, it may need to be replaced.
To test the ignition control module (ICM) on a Datsun 280ZX, first, ensure the vehicle is turned off and disconnected from the battery. Use a multimeter to check the resistance of the ICM's terminals according to the specifications in the service manual. Additionally, you can perform a functional test by checking for proper voltage output while cranking the engine. If the module fails these tests, it may need to be replaced.
Probably a bad ignition control module. You can take it off and have AutoZone test it for free. Have them run the test several times to get it good and warm.
it could be that the timing is a little off check the timing with a timing light, it could also be the ignition module which is very difficult to test on your own you can take the module to advance auto parts and they can test it for you!
To test a Geo Storm ignition module, first ensure the vehicle's battery is fully charged and the ignition is off. You can use a multimeter to check the voltage at the ignition module's power input terminal; it should typically read between 12-14 volts when the ignition is on. Next, check for continuity in the ignition coil and the wiring to the module, as well as any ground connections. If the module fails to produce spark or the readings are inconsistent, it may need replacement.
if you have the module off take it to a parts store(autozone/advanced auto,or whatever you have around your location) they should be able to test it for free. you may also want to check your pick up coil/coil and distributer.
It could be that the Ignition Control Module is faulty. There are known to go bad during the motor being hot, but once cooled down the engine will start. This is located on the front of the motor, underneath the the coil packs. You have to take the coil packs off, and unplug the ICM (Ignition Contol Module), and it will fall off from there.

We had the exact same problem with one of our vehicles. It would start when the engine was cool, but once the engine got hot it just shut down. It wouldn't start again till the engine cooled. The problem was fixed by replacing the module under the coil packs. It has to be tested while still hot to be able to determine if it's the problem, once that module cooled it tested just fine, but was bad. Hope this helps!
