2002 Suzuki SV 650 S won't start

I have a 2002 SV 650 bought it in January, and it was running. put it in the garage and now it won't start (may). replaced the battery. good crank, good spark. doesn't seem like it is getting fuel? never had this model before....is there a trick or common problem with the fuel? can't even find the fuel shutoff, is there one? not ready to tear into this bike as I know nothing about it yet and do not have a service manual.

Hi, Bwilliams239 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 choke
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.

SOURCE: The bike will start when I jump the battery then

Take the battery out of the bike and hook it to a charger. Make sure it is properly charged and take it to a battery store to have a load test performed. From your description, it sounds like the battery is shot and needs replaced.

SOURCE: bike wont start

Have you checked if the spark plugs gets sparks on cranking, check too if the spark plugs are getting fuel..i.e. are wet after cranking the engine.

SOURCE: My issue with my bike is constant fuel overflow,

Your petcock needs to be rebuilt (if parts available), or replaced, if it does not shut off the fuel. It also may not be saving reserve fuel , if gas is bypassing the ON position. You may also need a new fuel filter .Maybe add an additional in line filter. If you have replaced the float needles and the carbs are still overflowing you probably have a problem with rust in the tank. Have the inside of the tank cleaned or use a rust removal kit on the tank and see if this does not solve the problem. Try to avoid fuel tank liners if possible , they can cause more problems than they solve.

Go to the parts store and buy you a battery hydrometer, they are cheap, about 5 bucks. You can test the health of your battery with it. Just because it shows a full charge does not mean it has full power, the amperage it needs, your charger is only reading voltage. To test the charging system you will need a voltage meter...with engine running at 3500 RPM you should have at least 13.5vdc at the battery...
I hope this helps.

Check to make sure the battery is fully charged and that the fuses are all good. If you push the starter button and the solenoid clicks, the button is good. Take a wire and jump the two posts on the solenoid or touch the two cables together, if your starter works, then you need a new solenoid. If you hold the starter button and tap on the starter with a plastic hammer and the starter works you need new starter brushes. Anything else wrong with the starter and you need to replace the starter assembly , unless the manufacturer sells replacement parts so you can repair the starter. most manufacturers only sell replacement starter brushes but no other internal starter parts.

Charged battery.showed charged right away.bike wont start unless


Hi and welcome to FixYa,

The description "...series of clicks..." is significant. The battery is not putting out enough current to turn the starter motor. The best way to determine the battery condition is to have it load tested. However, considering eveything else, it would almost always be a failed or about to fail battery.

Incidentally, the alarm has been designed to have minimal current drain when in standby.

Good luck and thank you for asking FixYa.

My 2002 sv650 speedometer gives me incorrect readings, about 30-40% more than the actual speed


the sv runs the speedo from a front wheel speed drive and sometimes the tabs that turn the drive can bend or brake off giving a false reading so i would remove the front wheel and check that the two tabs are in good order and that the wheel drive is aswell.

Make sure your choke is fully in closed possition> Sitting up for that long could have allowed vanish to not allow it to seat and cause an overly rich condition
