welcome to the board. 
it may be the injectors. if they have never been serviced before, then it would make sense.
it's probably best if you set the stage a bit for us though. did this happen all of a sudden? was the car down for a little while and you're putting it back together now? is it a stock setup or have there been any mods concerning fuel or fuel management? that sort of thing ....

maybe try hooking up a test light or something similar to each one of the injector plugs and see what happens when you're cranking it. likewise, if you can set up a rig to test the injectors themselves to see what they are doing, that would be helpful, too.
if those tests check out fine, then you can start looking at the Microtech itself.

have you tried maybe moving the injectors around? maybe swap the primaries and secondaries?
.microtec would be out of my depth i think
if the plugs are getting wet, and it's not starting, then i would say check the Microtech.

well, if they lit up, then i would think they are getting the signal. in your response to DR Knight's post, are you saying that they are not getting wet? if so, then you may have your answer because you confirmed a signal at the injector and fuel at the rail. testing the injector yourself would require making something to test them. i've never done it. i've seen it done (in videos) and thought about building something, but have not acted on it. all in all, it's probably easiest (and best) to just send them out. i don't know what it would cost in NZ, but for what it's worth, it's not prohibitively expensive here.

always good to know your limits. if the plugs are getting wet, and it's not starting, then i would say check the Microtech.
