Switch parts with another 91-95 Saturn and drive both until completely warmed up to see which car displays any temperature sensitive problems.
start the engine if it runs its good
ignition module on what?
Many autopart stores have a machine to test it. The machines use a universal adapter to hook into the ignition control module. The ignition control module is in the distributor. If you mean the part that contains the ignition coil, when mine went bad I probed it with an ohmeter and then asked the parts store if I could test the resistances in a new coil before I bought it. Since the resistances of certain terminals weren't even close, I knew I had a bad coil.
The Distributer module on "92" S-10 Vin code "W" or "Z" is located on the distributer,you must remove the distributer cap to gain access to the ignition module. Once you have gained access to the ignition rotor it is always necessary to always test the module before replacing it.
Answer testing ignition modulenot all part stores have the ability to test ignition modules,a sure sign would be discoloration of the module or if the outside of the module has a softness to it if neither is apparent you could go to advance auto stores and they do have a peice of equipment to test your module, I used to work at a advance auto parts store
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.
Remove it and bring it to a NAPA store. They will test it free.
Take it to AutoZone, and they can test it
The easiest way to test ignition coils on a 1992 Mustang 2.3 is to use an ohmmeter on the leads going into the coils.
Symptoms of a faulty ignition control module on a 1992 Ford Aerostar van can include difficulty starting the engine, intermittent stalling, or rough idling. You may also experience poor acceleration and a noticeable drop in engine power. Additionally, the van may exhibit issues with the timing of the spark, leading to misfires or a check engine light activation. If these symptoms occur, it may indicate a need to test or replace the ignition control module.
To test the ignition module on a 2003 Harley Softail, first disconnect the battery and remove the ignition module from the bike. Use a multimeter to check the resistance of the primary and secondary coils according to the service manual specifications. Additionally, inspect the wiring and connectors for any signs of damage or corrosion. If the module fails these tests, it may need to be replaced.
I take mine to Autozone, they offer free testing of ignition modules.
