Fuel injection ont start

Ok,Sorry It's taken a while to get back to you as I wasn't sure where to pick up you comment from(on the site).My appoligies.

Any way to get back to your problem.

If you feel the problem is your injectors that are not delivering fuel,try placing a phillips screw driver on the injector & your ear on the handle,crank the bike over & listen for the tick of the injector solinoid.If there's a tick it's probably not the injection, If there's no ticking then it I likely you have guessed right & the injection system is the problem.

If this is so, most of the early(i'm not sure about yours)injected bikes have a small light in the injector control unit (or a injector fault light on the dash/instrument pannel) that you should check.If either is the case then it usually remains lit or blinks after the buzz of the fuel pump stops.The blinking type will usually represent a series of short or long blinks(like morse code)You note the series(usually long blink for 10,short blink for1) & check with a dealer/workshop manual to identify the code which tells you what component is faulty.

I would normally have sorted this myself & given you the exact procedure but my phone line was blown clean out of the wall in an electrical storm last week & it's not going to be fixed for a couple of weeks at least So I have generalised to try help you sooner.



If your injector was ticking follow these steps.

Your bike won't start. To fault find a no go situation on any bike I always follow the same procedure knowing that there are three systems involved in getting any engine running.These are the electrical system(ignition),fuel system & mechanical system.

I always check the electrical(ignition)first as its the easiest to check & while checking it you can sometimes get a lead on the problem if its not the electrical system.

To do this I remove the petrol tank & then remove then the spark plugs(keep them in order).

Inspect the plug looking for wear & colour. The colour of the sparkplug can often offer a sign as to what is going wrong.

If one or two plugs differ in colour this can often help to identify one or more particular cylinder/s that are causing problems.

Plugs that are say,black,dry & sooty is sugestive of a rich mixture which could be caused by things like a blocked airfilter/airfilter intake,poor combustion,blocked exhaust to name a few.Bleached white coloured plugs are an indication of not enough fuel,

Wet(with fuel) plugs suggest flooding or poor ignition(no spark).



Before continuing to the next step be weary if the plugs came out very wet(with fuel)as the bike could be flooded with fuel(this is common on carburettor models).

With the bikes kill switch OFF & standing well to one side tap on the starter for a few seconds & make sure fuel dosn't blow out of the cylinders.(Once i didn't do this firston a GPX 250 & the bike set alight.I put it out quickly & the bike wasn't damaged but it was a hell of a learning experience!)



Next I re-insert the plugs into the respective plug caps,lay them on the cylinder head or rocercover(so the metal thread earths to the bike) & crank her over to see that they all have spark.

If they do you can vertually count out an ignition system fault(as electronic ignitions 9 times out of 10 either work or don't).

If they don't you have an ignition fault & you'll need to chase this up first.



Assuming that the ignition tested ok I would then check your fuel system.

First check fuel flows from the tank,also a quick smell of the fuel can tell you if the fuel has gone off(yes fuel goes off).

On fuel-injected bikes (like yours) I then remove the hose that comes from the fuel pump(the one that goes to the injectors).

Supply fuel to the pump(using a long hose from the tank,a remote tank or preferabily if you can rest the tank back in place on the bike & reconect the fuel line back to the fuel pump inlet).

Now place the fuel pump outlet hose over a container.

Turn on the ignition & see that the pump actually discharges fuel out of the fuelpump OUTLET.

This has now tested the fuelpump.

If this is ok then let me know & I'll follow up the injection control moduel fault finding procedure for you as soon as I can

Again sorry for the delay I'll be anxiously be awaiting your reply
