SV won't start

Btw if the petrol smells like petrol and the bike has been used in the last year it's probably ok.

Also if you are going to check all of the plugs make sure the leads go back to the same plug hole if they have to come off.

Afaik FI bikes aren't easy to flood.

It might be worth you checking the other plug/s for sparks. You may have four plugs on yours, I'm not sure what year they went to four.

Also before you do that it's worth trying some jump leads if you can borrow them and you have a car. It's very possible that the battery is still not holding enough charge to start it. Also check the battery connections are tight and are in good nick.

K7 became 4 spark plugs, so that's not me. I've already researched flooding, but A) didn't want to rule it out despite it's FI and B) would like the knowledge of how to sort it anyway. Sorry for the inconvenience. I thought it would still be interesting to check, so my questions regarding how to resolve water in the fuel and a flooded cylinder still remain.

Ok, I'm alright then. Thanks!

is the fuel pump priming when the ignition is turned on?
What state are the plugs coming out in after a period of non start cranking? wet (fuel) dry?

you already have a spark. Assuming the timing hasn't have changed since it last ran: remove each plug, pour a teaspoon or 2 of clean fuel down the plug hole and go for a start, if it fires and chuffes over a few seconds then the issue is injection related ie fuel pressure/injectors etc. whatever it is, it seems common to both cylinders.

if it doesnt start then its very odd and its time to start checking spark/valve timing and compression.

i know its probably been said, but there IS deffinately fuel in the tank?

What is "fuel pump priming"?
The spark plugs I took out were dry after trying to start it.
What is "chuffing over"?

When you turn the ignition on is there "whining" type noise from the right hand below the tank?

Thats the Fuel Pump priming

If the sound lasts about 2 seconds, I know what you mean, and yes, it is priming.

Being a pointy and having fuel injection does it have a lot of sensors and voodoo that can stop the bike starting if something has worked its way loose? I don't know anything about the 2nd gen SV but a friend of mine had a sensor fail on his GSXR, was fine until he turned the ignition off.
All I'm suggesting is that if all else fails get someone with the diagnostic software and plug it up and check for any fault codes

Had my K6 failed to start this morning, spins but didn't fire. Suspected it was flooded (fiddled with at weekend) and yep, usual flooded engine clearing procedure worked a treat with FI engine. Fired up in no time after a big pop from the exhaust.
Procedure is open throttle full and press starter, close throttle rapidly when it fires to avoid over-reving

if the plugs are coming out dry, its very unlikely its flooding

you need to try running it with fuel down the plug hole and then decide what course to take from there.

there are only 2 sensors that would fail and prevent the engine running- crank position sensor, (which must work as there is a spark)
tip-over sensor would kill the spark and injectors and fuel pump (2 of which we know work)


Are you certain there is fuel in the tank?

are you getting the 'CHEC' display when you try and start it?

Given that it's now 2 days since OP last posted, what's the betting it was the killswitch after all?
