wont start Lexmoto Isca 125 Euro 5

[cassyj]

ugh i need help with my motorbike, battery was dead charged it bike now turns on but wont start. its not the spark plug, fuel is coming out of the pipe but not getting to spark plug, i think i can hear the fuel injector priming. it does have the engine management light on. but no codes are coming up on my scanner. 

 

i have no mechanical knowledge at all i'm a complete newbie sorry  

 

 

 

[cassyj]

maybe the kick stand switch? 

[fq-craigus]

Inhibitor of some description is where to start, and you say you have charged the battery but is it full voltage? 
you can only check fuel as far as the injector, you won’t see if it’s misting.

yeah i checked the battery with a multi meter and it was all good

That may not be the whole story. A battery can show 12v at rest but not be holding charge. Did you test it under load? 

 

You want above 12.5v at least. Anything lower says it's discharged. Put a headlight bulb on the battery and then test it. If the voltage drops then the battery either needs charging or replacing.

If you're able, try another battery. If you don't have one then connect another 12v battery to yours (e.g. a car battery) with jump leads. Positive to positive and negative to negative. Then try starting. If it starts then your battery needs replacing.

thanks both will pick some jump leads up

1. Connect the red positive terminal on the dead battery to the positive terminal on the live battery.
2. Clamp the black negative terminal on the live battery, but make sure you place the opposite negative clamp on a grounded and unpainted metal surface of your motorcycle. Typically, the chassis is suitable for this.
3. Start the motorcycle with the good battery. Do NOT start the car.
4. Allow it to run for a few minutes and then carefully disconnect the cables in the reverse order they were connected.

It’s important to place the negative clamp a safe distance from the battery because this connection often makes a spark and could cause a potential hazard. If your battery is a sealed Yuasa AGM battery, there’s almost no risk of fire, but keeping the negative clamp away from the battery is a best practice.

 

if you have one of those lithium battery jumper packs (get a small one for like £20 at halfords etc) and use the same way unless it says otherwise.
