Tiger 955i Help

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

 

As said earlier I had a Bonnie the same and it turned out to be I think a 02 sensor
