SV 650, no start issue?

Bought my bike around a week ago and it starts and rode fine for the week. Just today I tried to start and it just cranks. It started for a while and just dies (stalls) after couple seconds. After that it just kept cranking on every attempt to start. Suck out the old gas and used new Shell 91 and still no start. Old gas removed because the bike was sitting for a while by prev owner...but it did start and idle fine last week. Took out the plugs and looks worn but not in the worst condition. I would change the plugs tomorrow but just want to get an idea of what else there is. There is fuel going in because spark plugs are wet when removed. Air is coming in, because the plate on the throttle body moves. Could it be like a EFI relay defective, seen it in a car no start problem. Hopefully it would be the plugs but if you guys have any idea what else it might be, please post it up so I can look at that issue as well while I take the bike apart. Thanks!

have you tried charging the battery?
 
It is a new battery place into the bike before sold. I tired to start it many times and the battery drain out. Recharge the battery to its maximum, and start again, but still just cranking.
 
it is that one as posted....was there something wrong with the bike before?? Thanks

Well .... the seller did say that the battery had died on him from sitting for so long, so if I were I would get a new battery and try that out. Maybe check out the fuel injectors, make sure they're not gunked up. Also check the fuel pump, it may be gunked up as well from sitting for soo long!
 
The seller bought me a new battery into the bike. The bike ran fine for a week and started every time. It is just these couple days where it just cranks. There is another member here post the exact same problem on their GSXR bike. They said people with GSXR, the bike doesnt idle well in cold temp days...I guess Suzuki is just not good in extreme cold temps?

The seller was putting in a brand new battery. I walked away after thinking everything that could be wrong with a bike that sat that long without any love. The price was not that cheap to justify the extra work. Fuel system, tires and dried gaskets were my concerns.
 
I knew the bike needed tires...but was running fine every time I started...The fuel pump primes every time the switch is on as well. Guess I will switch over the plugs and hope for the best. Thanks

Sounds like it's flooded. See if there is any info on SV650 related forums for the proper flooded start procedure. It's typically twist throttle wide open and crank. Owners manual might be of help too. FULLY charge batter as well, if low, the starter steals all the powers from coils and it just won't start. Bonne chance, bonne apetite!
 
Not to be a jerk but charge the battery and leave italone until spring. If there still is a problem get someone who knows what they are doing to help you.
 
If the bike has one, check tip sensor, kickstand switch, check all vacuum hose has been connected

I've ridden 2 suzukis to 60k & never had a prob, stop bashing it cuz someone neglected it

The only (2) times my SV didn't start it was the battery. It was winter or the end of winter both times. Good luck, I hope you find the same.
 
You say you have fuel, are the plugs soaked with fuel?
You need to check if you have spark. Pull the spark plug, put it in the plug lead, ground it and crank the motor to check for spark.
A common issue on these is accumulation of junk in the plug recesses due to blockage of the little drain port, Mostly in the front cylinder. Use a piece of safety wire to clear out the hole.
 
Yes, when I pulled the plugs, it was wet with fuel on its tip. Also the plugs are pretty black on its electrode tip. It is just a rubber coil, so my guess like a car there would be a disturber (cap and rotor style). Could that be one of the reason as well? One more question, I got a bunch of car fuel injector cleaner that I have from work...could I use that on the bike, and possibly clean up the injectors? Or should I buy the cleaner from seafoam or motul?
 
Seafoam yes, change plugs yes.
 
There is no distributor, cap or rotor. It's DIS (distributless) ignition controlled by the PCM.
 
Try to give the spark plugs a quick clean with an old toothbrush or soft wire brush. Just enough to get some junk off of it and try again. You said you were going to get new plugs anyways, which is a good idea since the bike has been sitting. Plugs aren't that expensive and you only need 2.

Not sure if you have the necessary tools but a compression test wouldn't hurt since you're already taking the plugs out. I believe you can go to a PartSource or another similar store and borrow one for free.

svrider.com is going to have a lot more SV-related knowledge for you.

Good luck.
 
I've got almost 40k on my SV and never had a problem with it. I don't think there's much of a problem with the bike after having sat for only 2 years.

When you turn on the bike, can you hear the fuel pump priming?

It's possible that the two year old gas gummed up your injectors or something else. Are both spark plugs wet? If they are, then gas is flowing to both cylinders. I wouldn't worry about gas yet but I would still run some seafoam through the bike (gas tank additive, available at NAPA or Canadian Tire).

Then do the easy things first. Check for spark, clean the plugs, or preferably just replace them. There's only 2 and they're not that expensive. This way you know they're good.

Charge the battery completely. Someone posted that cranking will steal the current. This is absolutely correct. Make sure the battery is fully charged.

Try starting the bike. Twist the throttle until wide open to see if that makes a difference, however, these bikes are fuel injected and the ECUs do a great job of starting these bikes when cold.

Post up your results.
