Ok looking for some feedback. Stock 05-06 GSXR 1000, just installed in the car, stock injectors, ECU, ect. Turns over and tries to fire, has spark to new plugs. I pulled the Throttle Bodies and upon initial push of the start button it activates the injectors for one cycle..... Then they stop pulsing. I have 43 psi fuel pressure..... Any help would be appreciated!!! Chris B

Check your grounds.

Weak Battery?? Try starting it with a battery charger hooked up...

Fuel injector wires . Switch secondary to mains and mains to secondary

ECU fault, most likely ground or tip sensor trip. Can't be much wrong if it hits and dies.

It turned out to be the Tip Over Sensor.
