checking the fuel injection pulse's does anyone know when you turn the key on to prime the pump should the noid light kick on for a second to prime the engine with fuel?

When I checked on my Maxima it didn't light up when the key was in the II position only. While running it did flash/illuminate.
Sorry I've never used a noid light to test injectors. I wouldn't see why an injector would pulse and flood the engine with gas if the ignition hadn't been told to fire.

A very easy way to test injectors is with the car idling. Disconnect each injector, one at time. There should be a very noticeable change in RPM's or idle with the injector electrical disconnected.
Some engines do pulse the injectors for cold starting purposes.
