The resistance for a coil pack on a 2002 Mazda Millenia typically ranges from 0.5 to 1.5 ohms for the primary winding and around 6,000 to 15,000 ohms for the secondary winding. It's important to measure the resistance with a multimeter when the coil pack is disconnected from the vehicle to ensure an accurate reading. If the resistance values fall outside these ranges, it may indicate a faulty coil pack that should be replaced. Always consult the vehicle's service manual for specific specifications.

A coil pack can be checked for continuity and resistance with an ohm meter. But for heat or load failure the only way to check a coil pack is to replace it.
To check the resistance on a coil pack for a 2003 Trailblazer, first, disconnect the electrical connector from the coil pack and remove it from the engine. Use a digital multimeter set to the ohms (Ω) setting, and measure the resistance across the primary terminals (usually the two larger pins). The typical resistance should be between 0.5 to 2.0 ohms. If the reading is outside this range, the coil pack may be faulty and should be replaced.
To measure the resistance of a coil pack, set your multimeter to the ohms (Ω) setting. For most coil packs, a range of 200Ω to 2kΩ is appropriate, depending on the specifications of the coil. Connect the multimeter probes to the terminals of the coil pack, ensuring a good contact, and note the reading. If the resistance is outside the manufacturer's specified range, the coil pack may be faulty and should be replaced.
If you have an Ohm meter you will want to measure the resistance (ohms) of the Primary and Secondary sides of the coil pack and compare your readings to the Specifications for the vehicle.
To test the coil pack on a 1997 Oldsmobile Regency, first, ensure the engine is off and disconnect the negative battery terminal. Then, remove the coil pack connector and inspect it for any damage or corrosion. Use a multimeter to measure the resistance across the primary and secondary terminals of the coil pack; refer to the vehicle's service manual for specific resistance values. If the readings are outside the specified range, the coil pack is likely faulty and should be replaced.
On the Millenia, each plug has its own coil; there is no distributor. The coils are connected directly to the spark plugs on each cylinder.
The coil pack could be weak, or break down under load or heat. The coil can be basically checked with an ohm meter for resistance, but the only way to know for sure is to replace it.
If it is on a 1996 Mazda millennia or similar year model, the coil packs on the 2.3 engine on the front are simple. If they are on the back this is a little tricky getting to them. Some wiring harnesses need to be moved around.
Coil packs can not be checked for heat or load related issues. They can be checked for proper resistance with an ohm meter.
The spark is looking for the easiest path to ground, you might have an issue with either your plug wires or plugs that is causing too much resistance. Also your coil pack might be going bad.
To check a coil pack on a 2001 Grand Cherokee, first, ensure the engine is off and the keys are removed. Disconnect the electrical connector from the coil pack and remove it from the spark plug. Use a multimeter to test the primary and secondary resistance of the coil pack according to the specifications in the vehicle's service manual; if the readings are outside the recommended range, the coil pack may need replacement. Additionally, inspect for any visible damage or corrosion on the connectors.
