Hey everyone, new to this forum, and want to apologize for my broken English in advance, but still wouldn't mind to get some help form you guys :)

So heres what happend;
Car has never had any starting issues. Two days before the problem- run out of gas while was talking to my friend with the ac on, tried starting it a couple of times after, engine was running very rough and as soon as I stepped on gas it was dying. Went to gas station, grabbed some gas and filled it up, car was running fine after for two days. Recently, got home and park my car. On my way to get myself some tea, I noticed in my window that the little led on my left taillight was blinking insanely fast, but no other light were on. I've never seen anything like that happening before anywhere. So I got out to check what was going on, as soon as I get to the car I herd really loud and fast annoying clicking noise that seems like was coming from ipdm box( relay clicking), when I got inside I realized that I forgot to turn ignition OFF, it was in ON position, and it's been like for for good 2-3 hours, so that and my lights that were on drained my battery complitely dead. I decided to disconnect the battery and leave till next morning.
Morning after, hooked up the battery and tried to boost it up with my neighbors car - no luck. Car was cranking but no starting, then I though it wasnt getting much juice and went to local store to
pick up battery booster and charger. Hooked all that stuff up and still no luck. Car cranks with normal speed, but still no gas and no injector pulse I think...

So what was done, and since I have no many tools, not much was done : checked all the fuses and relays; replaced IPDM; no DTCs stored in memory; pulled out three spark plugs(changed then 10k km ago) and coils, no spark and no smell of gas at all; disconnected the fuel line, tried cranking and fuel was coming out, not sure if the pressure is withing the specs, since have no fuel pressure gauge; tried disconnecting cam sensors, and cranking without them, no luck; took up crank sensor and cleaned it up, measured resistance, seems withing specs; got constant battery voltage at all coil.

Anyone please, any Ideas ? Thanks

Yeah, that sounds like a hot mess going on. Have you checked the fuel pump for proper voltage?

Otherwise I would start digging through the FSM: http://www.nicoclub.com/infiniti-service-manuals
