No Spark When Engine Turns Over

Troubleshooting Steps

If your Honda TRX400FW Foreman 400 engine cranks but doesn't produce a spark at the spark plug, follow these steps:

1. Check the spark plug for damage or fouling. Replace it if necessary.
2. Inspect the spark plug wire for cracks or breaks. Replace it if damaged.
3. Test the ignition coil using a multimeter. The primary coil resistance should be within 0.5 to 1.5 ohms, and the secondary coil resistance should be around 5,000 to 15,000 ohms.
4. Verify that the ignition module is providing a signal to the ignition coil. Use a voltmeter to check for voltage at the coil's positive terminal.
5. Inspect the ground wire from the ignition coil to the frame. Ensure it is secure and clean.
6. Check the kill switch and throttle position sensor. These components can interrupt the ignition signal.
