The injectors are merely open/close valves. They have a constant power at one terminal and a variable ground through the ECU to control how long it stays open.

Find out what your missing....

Do you have 12v at the injectors?

Pull up a wiring diagram and follow the path between the FI fuse and the injector. Somewhere it's loosing the voltage.

It appears everything is okay & no possible voltage leakage..the latest i have learnt is, this bike is an accident bike,it had afatal accident one and half years ago,but it had been rebuilt to date with anew ECU unit as well

Like i highlighted earlier,the fuel pump primes pretty well,pumps fuel to the rails pretty good but it never releases from the nozzles as required...amongst the tests we carried out lately it somehow released the gass & engine ran & raved for over 20mins nonstop but we didnt take it to the road for arun instantly. We stopped the engine to fix the brakes 100% before hitting the road..tried to start the engine again it refused to release fuel again & "check engine" signal appeared again
