Help Needed

Hi lads

looking for help!

I replaced the female couplers on my 04 tiger 955i the bike fired up first time (happy days) the next day I fire her up she cut out after 2-3 seconds done the two more time and the engine management light came on

this light is staying on and she turns over and won’t fire up any ideas much appreciated

 

This is the problem bike will not start she tries to turn over but will not fire up

I also changed the air filter to a K&N just wondering would that make any difference
