I don't think there is a way to check this electrical component other than trying another one. A cheaper alternative is to get a used one at a junkyard and try that first.
Check the ignition control module.
Ignition control module, pickup, coil, keyswitch, loose connections. With ignition key on (engine not running) check for 12v (battery voltage) present at Ignition Control Module (pink/black wire) 91 cavaliers use two separate coil packs so check if no spark on all 4 cylinders. Check for a bad Crankshaft Position Sensor (CPS) Should read 800-1200 ohms between the two leads. If it's open or reads very high resistance - replace. It should be putting out a .8 to 1.4 volt ac signal during cranking. If the Ignition Control Module does not see this signal - no spark.
check the ignition control module.
it can, but i would check the ignition control module first....then the crank sensor.....
Diagnosing the ignition control module is done with a diagnostic scope. These scopes can range in cost from a few hundred dollars to several thousand, so the most economic way is to take the car to an auto repair shop.
check ecm engine controle module icm ignition control module or crank angle censor if is a dhoc distributer if shoc>>>>JAC
I can't make any promises, but I've got 94 Chevy using OBD1, like yours probably has too. In my manual this is what it says: Code 42:Ignition Control Module - "Check the wiring and connectors between the ignition module and the ECM. Check the ignition module. Replace the ECM".Code 43:Electronic Spark Control - "ESC module is not receiving a knock signal from the knock sensor. Check the knock system sensor, or the ESC module. Have the module checked by a dealer service department." Hope that helps, good luck!
The Ignition Diagnostic Monitor (IDM) information is sent from the Ignition Control Module (ICM) to the Powertrain Control Module (PCM computer). The PCM monitors this information to check on the Ignition System. The ICM is Black in color in 1994 and newer Ford Trucks. Do not use a Gray module as it will cause the PCM to output a code of a missing IDM signal. Auto Part stores have the wrong part listed for these trucks.
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.
To check the ignition module on a 1993 Dodge Stealth, start by disconnecting the battery to ensure safety. Then, remove the ignition module from its housing, typically located on the engine. Use a multimeter to test the module's resistance according to the specifications in the service manual, checking both the primary and secondary circuits. If the readings are outside the specified range, the ignition module may need to be replaced.
To check the ignition module on a 1989 Volvo 240, first ensure the ignition is off and disconnect the battery. Then, locate the ignition module, which is typically mounted on the driver's side fender. Use a multimeter to check the module's resistance and ensure it falls within the manufacturer's specified range. Finally, inspect the wiring and connections for any signs of damage or corrosion, and consider testing the module with a known good unit if issues persist.
check your plug wires, then your coil packs, then your ignition module.
