Got a call back today confirming that it is getting both spark and plety of fuel pressure yet it still won't start. He doesn't know what the problem is either; only that it's probably computer related. He doesnt want to just start swapping parts (got to give him credit for this) and suggests the Nissan dealer would be better equipped to test it. I really, really don't want to take it to a dealership if I'm able to avoid it.
Has anyone else experienced anything like this?
Is there more than one electronic control or ignition module? Might it be worth it for me to just replace it?
If not the computer itself what else might make it not function?
Any ideas, anyone?

if its getting spark and fuel then the ecu is fine because you are getting all necessary components to start because the only fuel related thing the ECU controls is the injectors and it gets feedback from the timing to know when to fire the injectors. the fuel pump is just connected to the ignition switch and when you turn it to the on position you should hear the fuel pump kick in which is proving you are getting fuel. but i cant really diagnose without seeing this for my self
