My 2000 V-Star Classic has been dormant since Oct. Now it turns over but won't start. I used a fuel conditioner and the battery is fully charged.

check all fuses then the ignition module with a timing light then the fuel pump one of these will fix the problem

If the engine cranks but won't start, someone will need to figure out if you are lacking fuel to the injectors or spark to the plugs to proceed with diagnosis.

-do you use the right key? (thick brown/black colored) after aou turn the key on, does a light go on on the dashboard?
- seems to be an issue with the lock code of the key (wrong key)
then the engine immobiliser does not allow to start..

your starter is bad.

Have you cleaned the Fuel tank recently? some times even under excellent care you can get gunk built up. also have you checked spark plugs

hey Joseph,, have you had the battery load tested?? Have the CCA (Cold Cranking Amps) checked.. O'Reilly, Autozone, Advance Auto..etc can load test your battery... 12 volts only wil not get much done... you need amperage and 13.6+ volts...

sounds like maybe wire off to switch.
