Hi can anyone help plz bike turns over no spark checked immobiliser, sensors no f1 code im thinking ecu can it swap sraight in ?

 

Dan don't jump straight to the ECU it can be an expensive mistake as a side note you can swap out the ECU but you'll need at least the Red Master key which is coded to the ECU.
When you turn on the Ignition do you hear the Throttle Body actuator and the Fuel Pump cycle ?

 

hey Kev the start up cycle sounds ok , long story short had bike two weeks was running fine then evey morning wouldn't start when it did high revs wasnt kicking in now nothing.left with mechanic he's checked all sensors and what haves.still nothing

 

Get your Mechanic to check Fuel pressure and carry out a flow test.
Attached a spec sheet.

 

Some good info.
