'06 Sedan won't idle

**************EDIT: SOLVED, FIXED (fuel pressure regulator was bad)***************
This car just started turning into another project car, I can see it already..
I have an '06 Sedan with slightly over 120,000mi. Besides my clutch slipping prior to this unfortunate event
, my car was sputtering and had a loss of power while driving home from a friends house after two hard starts earlier in the day. Once I got to my house, my car never started again no matter what I did. No SES codes.. At least from me doing the pedal dance trick, I just get the four 0s. I had already had a set of NGK Iridium IXs in my garage, so I installed those to no avail (not that I was thinking that would be the fix). I picked up both bank's cam position sensors (OEM from Nissan dealer) yesterday and replaced them... nope. New fuel pump comes in today. So that's next... Tomorrow the crankshaft position sensor comes in. I'm posting to keep track of this proccess and leave it open for helpful tips because I NEED my car. This is my daily driver.
*** On a side note, yesterday after installing the sparkplugs, it would turn over and run for a few seconds sounding like complete ****, but eventually the RPMs would fall back to 0 and it would die. Extremely rough idle. It probably needed the plugs anyway, so I'm sure that helped, but had nothing to do with the root problem.
SO FAR
* sparkplugs (no oil anywhere, so valve covers are good)
* both camshaft position sensors
* fuel pump
* crankshaft position sensor
POSSIBILITIES
* MAF
* ignition coil plugs
* fuel pressure regulator
* ???
HELPPPP :/

Thank you for the reply..
& by the way, no mods. I had an oil catch can & thought I may have developed a vacuum leak so I took it off, which had no effect.

..you can't just buy an all in one unit like you can with the coupe. The sedan fuel system is slightly more complicated, and you buy all the pieces separately.
*** I picked up a fuel pressure tester for rent today from autozone, and I want to check the fuel pressure when starting, etc. I know I think it's supposed to be ~41 psi I believe. Has anyone done this before? Where did you hook it up? Normally there's a bung pre-fuel rail, but there isn't from what I can see.

Replaced fuel pump about 30 minutes ago, ran okay for about 3 minutes before it started stumbling, misfiring, etc again. No go on the pump.
I assume starting it without the MAF will eliminate that as the problem, yes? If it goes into safe mode correctly? Please help, forum ):
EDIT: Wouldn't start with MAF unplugged. Won't start either way. HELPPP

Know anyone else with a G that you can use parts off of to test? Like MAF
Also have you checked for vacuum leaks? Must be a big one if you car stumbles like this.
OR could it be that you just have really bad gas?
