Pointy won't start.

[steve1971]

Hi all i'm new to the forum and this is my first post and am in need of dire help.

I commute on my SV650S 2004 model and had it a year and had no issues what so ever until weds, came back sunday from a short ride out and the bikes been out in ALL weathers storms ect you name is.

Weds afternoon had a hot date with a chick and it wouldn't start....even when jumped from a car battery.

Checked the following

ALL electrical connections
Plugs ( new one coming tomorrow just in case) had spark
Fuel pump comes on when FOB pressed
Fresh fuel in tank
clutch and side stand switches work
and freshly charged battery which was replaced in April/May this year.

Only thing i noticed is that both headlight bulbs had blown ???!!!???

Thoughts from the collective much appreciated.

Cheers

Steve :rolleyes:

Should turn over if the kill switch is active ?????? Surely ? Battery on charge at present

[steve1971]

also even in neutral i have to pull in the clutch to start is this normal ?

[Tomor]

It wouldn't turn over if the kill switch is in the 'off' position. Yes you also need to pull in the clutch to start it .

Hmmmmmmmmmmmm will put cleaner in the injector tomorrow fit the new plugs and wd40 everything ?!?!

Spark is good can't understand is there and diagnostic reset or something or a safety bullsh*t because the head lights blew ?

Let's be really clear on what is and is not happening.

From what you've written above:
1) Bike was working fine, left for a short period, nothing has happened to it between it running and not, however trivial.
2) The bike turns on with the ignition and display lights up, fuel pump can be heard to prime.
3) The bike turns over strongly on the button
4) There is a spark from both plugs when removed and grounded against a good earth.
5) The bike does not splutter, cough or smell of fuel.
6) The headlights have both blown.
7) There are no errors shown on the dash when the bike is turning over or before the starter button is pressed.

Does all of the above sound correct, or is anything not as above?

More importantly, were you able to find another way to get to that date? :D

The bike did smell of fuel from the exhaust pipe, if the battery is faulty and not enough amps maybe the spark isn't strong enough. But is should of started via a jump from a car!

Other thought is what about automatic choke, throttle sensor ect

[steve1971]

Date is for ssturday now so no pressure i live in the sticks

[jambo]

Please confirm exactly what does and doesn't happen.

Generally speaking if the battery is strong enough to turn the motor over, it's got enough power to make a spark, but unless we get methodical about what is and isn't happening here we're all just guessing and listing components.

Ok

key in turn on

press fob pump goes

pull in clutch push start

engine turns over and if I'm lucky

One cylinder sounds it wants to fire !

If it was a carb engine I'd say it's over choked and rich which is why i asked about automatic clutch maybe

[Fen Tiger]

Maybe water in the fuel. If the bike has sat in the rain with maybe an obstructed fuel tank overflow pipe water could have got into the fuel and collected at the bottom of the tank. Worth a check anyway.

[steve1971]

Its nearly empty ill drain and add it to my list before starting

[650]

You've mentioned all electrical connections, but are all the fuses in good nick? Fuse box not corroded? Battery terminal connections in good condition? If it's a pointy then I wouldn't be surprised if the bike won't turn over without lights...I'm sure (many moons ago) that I read most modern bikes are dependent on the lights and clocks working for a bike to fire up, the curvy has a light on/off switch like my old carbed VFR750. Just a thought, not saying it's fact :)

[steve1971]

Kind a thought that new bulbs in tomorrow too, i also have a vfr and had 6 of them and know them inside and out, plus a 1972 ironhead sportster

my bike doesn't have light on off switch

[curlylee]

check tip over switch its a little black box under seat ,it should say up/top on it,mine came loose and fell on its side so bike would not start

[Red Herring]

I'm a bit confused by this "press fob, pump goes" bit. The pump should be heard priming as soon as you turn the ignition on with the key. Is this an alarm fob you are talking about? If so are you not supposed to deactivate it before turning the ignition on?
After the engine has failed to start are there any fault codes displayed on the dash such as F1, or a little red light flashing?

What does it look like i have no manual

[Corny Gizmo]

My money is on this "fob"

Sounds like an immobiliser that wont stop immobilising

[Red Herring]

It's a little black plastic box about 20x15mm that sits in a rubber sleeve that is in turn attached to the battery box under the seat. It will have a couple of wires out of it and it needs to be horizontal to work. The idea is if the bike falls over it will cut out the engine. I'm pretty sure the engine won't even crank over if it's not in place, but you definitely get the F1 warning.

[steve1971]

Gonna tackle the sv today ?!!

[steve1971]

I have noticed there was a ****ty scotoiler once connected found the remain of a vacumm tube but cant see where it was connect on the intake?

Also is there a automatic choke or does the injector just change the amount of fuel input via a sensor.

[steve1971]

Sorted i think new plugs and cleaned collections fresh charge and new fuel. ....probably an injector air fuel issue

OK, in your first post, you said you cleaned the connections, installed new plugs and fresh fuel... and it wouldn't start. Now it will?
If there was an issue with the fuel injection, what corrected it? Or did it heal up on it's own? I like heals up on its own repairs.

[Sid Squid]

No actual choke as such, FI system has ECT and IAT sensors which allow map to alter injector duration, and secondary throttle valve actuator has a cam on its spindle that cracks the primary to lift tickover.

[ManMango]

Speaking out of Naivety here but could this have been anything to do with TPS/Idle problems? combined with cold temperatures maybe these just weren't sitting where they should have been?

When I recently did my TPS adjustment I moved the sensor too much one way and got my idle all out of wack as well. Had real struggles starting it until I got all this straightened out. A fresh day and a charged battery got it sorted no problems.
