Question about 2002 Harley Davidson FLSTC - FLSTCI Heritage Classic
Hi Franz, when checking for spark the CKP needs to measure the compression bump in order to send the correct signal to the ICM/ECM so always check for spark with either a third plug grounded or lift the end of the plug boot 1/2 " off one of spark plugs that are in the head. and the usual suspects are:
1. Fuel tank empty
2. Fuel supply valve turned off.
3. Fouled spark plugs.
4. Engine flooded with gasoline as a result of over use of enrichner.
5. Fuel valve or filter clogged.
6. Vacuum hose to automatic fuel supply valve disconnected, leaking, or pinched.
7. Discharged battery, loose or broken battery connections.
8. Loose wire connection at coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, spark plug cable connections loose,
or cables connected to wrong cylinders.
10. Ignition timing incorrect due to faulty ignition coil, ignition module, or sensors " Manifold Absolute Pressure" "Camshaft Position Sensor" "Crank Position Sensor" "Brake Apply Sensor
11. Engine lubricant to heavy ( winter operation )
12. Sticking or damaged valves or push rod wrong length.
13. Primary cam sproket spline sheared or missing spacer.
14. Security alarm system not disarming.

Check first the state of the cables to be sure. You may also just need the terminals to be cleaned. If you have checked the plug itself the problem may just be with the cabling or the coil. Check for blown fuses and relays to be sure. Check also the battery. It may be a weak battery. Try to jump start the bike using jumper cables connected to another bike to see if you can get it started, if it starts it could be a battery getting weak. Otherwise it may be the coil that needs checking.
Check also the kill switch. You may also need it cleaned. Otherwise check the electrical components mentioned above.
