The 1996 Chrysler Cirrus 2.5L uses individual coil packs for each cylinder. Troubleshooting ignition issues on this engine involves checking:
* Coil packs: Inspect each coil pack for cracks, damage, or corrosion. Test them with an ohmmeter to check their resistance. A bad coil pack will prevent ignition in the cylinder it serves.
* Crankshaft position sensor (CKP): This sensor is crucial for the ignition system. A faulty CKP sensor will prevent the engine from starting or running smoothly. It needs to be tested or replaced if suspected.
* Cam Position Sensor (CMP): Similar to the CKP, a faulty CMP will disrupt ignition timing.
* Ignition control module (ICM): While less common, the ICM can also fail, affecting ignition.
* Wiring: Check all wiring harnesses, connectors, and grounds related to the ignition system for damage or corrosion.
* Power distribution: Verify power is reaching the coil packs and sensors.
Instead of replacing a distributor, you'll need to diagnose the specific failing component within the ignition system. A simple visual inspection and checking for obvious signs of damage (broken wires, burnt components) is a good first step. You'll likely need a multimeter to test the sensors and coil packs to determine which part is faulty.
Here's a general approach to troubleshooting:
1. Check for spark: Use an inline spark tester to check for spark at each spark plug. This helps pinpoint which cylinder(s) is/are not firing.
2. Check the CKP sensor: This is a common point of failure. You may need a specific tool or a diagnostic scanner to check its signal.
3. Check the coil packs: Visually inspect and then test each coil pack individually with a multimeter.
4. Check the ICM (if applicable): Access may be difficult and testing may require specialized equipment.
Before attempting any repairs:
* Consult a repair manual: A factory service manual or a Chilton's/Haynes manual specific to your 1996 Chrysler Cirrus 2.5L is essential for detailed instructions, wiring diagrams, and torque specifications.
* Safety first: Disconnect the negative battery terminal before working on any electrical components.
If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic for diagnosis and repair. Improper diagnosis and repair can lead to further damage.
