Just took my bike out of storage...
Went through my usual post storage prep but I can't get it to start...

Battery is good - 12.7
Fuel is getting to the throttle body
Plugs are sparking fine
But no fire so to speak...

I can squirt fuel into the intake and crank it and it fires up fine for a split second...

I'm almost certain the problem involves no fuel to the engine...

Any ideas what I can to to check the injectors/pump???
I fi:dunnond it hard to believe both injectors would be clogged...

Thanks!
 
Could be a problem with the ECU not sending the signal to the injectors to squirt? What year bike do you have? On the pre 2004 I think you can get the fault codes to show up on the dash by connecting the diagnostic block under the riders seat.
 
Can you hear the fuel pump prime when you turn the bike on :confused
 
have you changed the fuel in it? Our kids VFR wouldnt start after being laid up for 3 months, put new fuel in and bingo, old fuel still worked in lawnmower just fine.weird
 
fuel crystalises as it evaporates and can leave a grainy sugary like depsoit behind. If it's been in there more than a few months it's probably knacked.

if it's old try new fuel and try holding the throttles wide open when you turn it over but be ready to close them quickly if it catches. The Tps will tell the ecu to dump fuel into the throttle bodies and more often than not it will dislodge any blockage at the injectors assuming there is one. if it still don't start after a few tries don't keep labouring it. You will have to investigate more by removing airbocx lid and checking for injector spray down the tb inlets etc.
 
LOL, i know, best bit was i knew that from off the Zone, whats all that about. you watch it wont be the fuel and i`ll look a :jack, again :eatcorn
 
Haaa!! im watching this like an hawk now ST ready to pounce when he says its something else :laugh
 
:scared, same here, not a good feeling, think i should edit all of my previous replies on this thread :pirate
 
superTed with your new found wisdom do you have an answer to Global warming ?

Much wisdom flows from your mouth young jedi it does.

how we shall laugh when it turns out to be that the tank is empty and we look like twonks. Again ! :nana
 
Not the kill switch is it, might be a daft question but I know i've done it before without realising :dowhat
 
If yer disconnect tank fuel line coupling and hang it out the side of frame..then turn ignition on, the pump should fire and pump fuel...if this is fine, then gotta move on down the line to next point of call. Highly unlikely 2 blocked injectors. Stale fuel loses its calorific valu and will not ignite if too old.
 
agree both injectors unlikely to block. But would a cold bike thqat's not been started in some time start on one cylinder ?

He stated there is fuel at the Tb's so i think we can rule out fuel pump issues.

if you have fuel at Tb's but non entering cylinder the injectors have to be an issue either not firing or 1 or more blocked.
 
Would ECU diagnostics show this mate? Injetor trigger pulses?? ..its getting out of my league here.
