Number Fault Check
1 Hard to start Electrical system fault
1. Low battery with not enough power
2. Check battery for loose terminals
3. Starting fault
4. Ignition system fault
5. Spark plug carbon deposit and tarnish
6. Improper gap of spark plugs
7. Spark plug insulation burn out or electrode short circuit
8. Burned out Ignition coil
9. Solenoid valve damage.
Handling method
1. Check all ignition wires to sparkplugs, make sure all are on secure.
