What to Do When the Car Suddenly Fails to Start?

[LeJocelyn]

Here are the solutions when the car suddenly fails to start: 1. When neither the horn nor the headlights respond: Use a wire to test for sparks at the starter's connection point. If there are sparks, the fault is likely a short circuit in the wiring between the starter and the ammeter. If no sparks are found, the issue may be due to insufficient battery charge or wiring faults. 2. When testing for sparks with a screwdriver at the ignition coil's negative terminal: If sparks are present, you can test between the distributor contact arm and the base plate. If sparks occur here, the fault lies with the contacts. You can use a points file to adjust the contact gap and eliminate the fault.
