Bought a 53 plate z1000 last August,intermittent fault with immobiliser i think,took back to shop and they checked the alarm system and replaced the control box.problem seemed to go away for a while.Went for a run on Saturday and the problem has re-occurred.When the ignition is turned on you can't hear the fuel pump.Any ideas or has anyone experienced similar problems,any info would be of help.The alarm is a meta system.
