A bad ignition module is usually characterized by several frustrating symptoms. A classic example is when the engine will start, but when it gets hot, the ignition module's electrical properties change, cuasing the car to die suddenly, but restart after several minutes of cooling. Some people have reported pouring cold water on the ignition module causes it to start when hot (mearly by cooling rapidly). Another way to test for this is to allow the engine to run for a total of 30 minutes, then gently tap the module with the back of a screwdriver. If the car fails, this is usually the source. Sometimes the car will not start at all, but this should lead to checking the ignition coil first. This is usually characterized by no spark, no combustion, but good power (or weak power) into the ignition coil. This is usually checked first, as both are common problems, but the ignition coil is usually 1/3 the price (or less) of the (often very pricey) modules (especially for later models). Basically, check for spark, if you dont have any, keep going back until you have checked the ignition coil, distibutor, ignitor, module (in that order) and any grounds, resistors, capacitors, etc. Check all for power in, out, positive, negative, and power out. Use a test light, a voltmeter (multimeter) and get a book for your car from the auto parts store.
