Suzuki SV650S Won't Start

[SamuraiBikes]

Hello all,
I have a 2007 SV650 that has been sitting for well over 6 months while I was out of the country. It had always run perfect up to this point.

When I got back I of course tried to start it, with no success. I replaced three spark plugs, drained and replaced the old gas, and put in a new battery, all to no avail. The closest I have come to getting it running is when I tried it with starting fluid and then it revved high or two or three seconds.

Any advice is much appreciated!

Also, I really don't want to put any more money than I have to into this bike. I would like to sell it as soon as its up and running.

It seems unlikely a component failed on its own while unused, but you never know.
Was it stored in a dry secure place?
Any chance a mouse or something chewed wires?
Corrosion can soon take hold out of sight and weaken crucial circuit connections, especially if it's been out on salty roads.
Main thing which will help is fast as possible starter motor so jump leads to another vehicle are a good idea.

I would bet on a fuel problem, since it fired on starting fluid.

Gummed-up carbs, stuck float valves, blocked jets, etc.

Worth a strip-down to check?

Keep flicking ignition on and off to allow the fuel to prime (u will hear high pitch whine).

Jump start it from a car.
Keep cranking it. It should eventually fire. These f.i systems arebrilliant compared to old carbs.

Also could try opening throttle while cranking.

Nothing should need to be touched.

How can you change three spark plugs on an engine that only has two?

Anyway, you got no fuel pressure. Turn the ignition on then turn the red switch off then on again a few times. Every time you turn it on you should hear the fuel pump run for 2 seconds. If you don't then either the fuel pump is stuck (unlikely), the fuse is blown (more likely) or if you have an alarm/immobiliser, it has a failed relay (most likely).

Is each cylinder twin plug? Or did that come later?

First, thanks to all who responded. Really appreciate it!
I don't know how to respond to each post individually so I will try to do it here.

So, doggone: My bike was stored outside, but it had a bike cover on every day. I have several cats around the house so I highly doubt it was a mouse or something chewing through wires. It has never been on salty roads and I think the fact that all lights and other electrical components seem to work fine that corrosion is probably not the culprit. I have hooked the battery up to a battery charger and car battery (while car was off) and I get the same result as with charged bike battery.

Taught2B: I think you might be onto something. When I removed the fuel tank, I expected gas to leak out the lines that I pulled off, but not a drop did. Also its a 2007 so does that mean it doesn't have carbs? What would be the best method of fixing clogged lines?

Paddy: Ditto. I think.

Roger: I'm not sure exactly what five quarter means. I think I hear the fuel pump running though when I turn key to start and switch to on position.

Taught2B again: No codes displayed, but fuel lines are starting to sound suspicious.

MystRider: I did this a lot over the past few days. Also hooked it up to car and cranked repeatedly. No go. And Yeah, I gave it a good bit of throttle as well.

Pete: Pretty sure it has four, two for each cylinder. I have tried your suggestion many times over and can hear the fuel pump running. Is the failed relay only if the pump is not running?

Underrated: Pretty sure both cylinders are twin plug. Not 100% positive thoough.

Roger: I was trying to avoid answering this because its a little bit embarrassing, but honestly, I don't know where the fourth plug is and can't find it.

Thanks guys! Hope to hear back!

Roger: I actually already took the tank off and removed the fuel pump. It looked pretty good to me (much cleaner than the one in the vid) but I don't know exactly what to look for either.
I also did disconnect the hose coming from the tank while the tank was back on the bike, with fuel pump back in tank of course. I could hear the pump running, I think, but no fuel leakage. I think either I didn't disconnect the line you were thinking or injectors maybe.

Pete: As I mentioned above, tanks had plenty of gas while I was away (even though I think my brother ran it dry then put in low grade gas several months ago), so I was the one that drained tank of that gas and replaced it with higher grade fuel.
I don't know exactly what the purpose if, or what a powercommander looks like, so I'm gonna have to say no.
And there no FI light coming on.

[Pete.]

Pop the fuel line, give it a lube with some oil and push it back on firmly. Make sure it clicks home. I remember someone having a problem with one of those where they thought it was fully home but it wasn't.

My post, I stay. Lol. Also, does that mean you don't have any ideas as to the issue?

[BTTD]

Was there any sludge in the tank? Have the in tank fuel hoses degraded to mush and blocked the fuel filter?
I'm assuming that the fuel filter is in the tank near the pump as I'm not familiar with the SV, but have had that happen to me on an older BMW. Bike wouldn't start after it had been laid up for several months, but in that instance it also killed the fuel pump.

Well done, insulting the one person who could probably help you more than any other. Regularly helps others such that he's given up time to help strangers at the side of the road.

We've all made that mistake. I once scoffed at someone having 4 spark plugs sold to them at service for an NTV600. I was soon put right!

Pete won't lose sleep over it, you might!
