Can' t figure this out replaced tps,fuel pump,filters,and plugs. The battery has a full charge.At first start it fired right over and ran very smooth the bike then stalled and has not started since.it will turn over but won't fire. The pump will prime but I keep getting a buzzing sound.the battery was disconnected but I see a....S335 code when when I put the battery back ......HELP!
I've had a 99 for 13 years now so I know a bit. If your engine's cranking at a normal speed and not starting you have 3 possible issues- Compression (not likely if it was just running), electrical, or fuel. Check the simple stuff first- Is you fuel tank vent clear? Check all you fuses, pull a plug and verify you have spark. Verify fuel delivery-pull the hose off the fuel pump & put in a can & crank the engine(10 ozs in 15 sec is OK).99s are voltage sensitive- I've found most issues with early Vics are battery or grounding related-get a volt meter & if you can do a load test on the battery, has to be 12.6 minimum-sometimes they seem ok but a new battery cures the issues. Check the main ground at the left passenger's peg and make sure it clean & tight. You have to access the fail codes so I don't know what your seeing, the fail codes read 1:1, !:2, 2:2, etc.
