Question about 2002 Yamaha TT-R 225
I have a Yamaha ttr225 I have spark and fuel but won't start what do you think might be wrong for it not to start
Hi, Chavezpedro7 and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
14. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
15. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
16. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
17. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
18. Faulty neutral, clutch lever, or kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.
21. Tilt sensor needs a reset.
22. Security system not disarming alarm needs a reset.
23. Check for engine trouble codes.

The cylinder is the coil. It might be bad but it is expensive and you would not replace it till you know for sure there is no spark. You can take the plug out and then put it on the wire and ground it against the engine while a friend cranks the starter. Look for the spark flash. Make sure the kill switch is in the "on" position.
If that shows a spark then you will need to move into a different line of troubleshooting. I always recommend that people buy a Clymer manual.

The only fuel filter that all bike should have is in the fuel tank if you have open stop res. tap, or you might have dirt in the carb. some bikes have a cut out switch on the side stand if you have one disconnect it and try again.
