91TT Problems HELP Please

OK so to start with I was coming home after working a 24 hour Staff duty shift and my z just stalls out like I ran out of gas (Still have a quarter tank of gas). I was a little suspect about the injectors before this happened so I got it towed home and ohm'd out the injectors. 4 or the 6 ohm'd out bad. So online shopping I went. I replaced all of the injectors with the new style injectors and tried to start it up and nothing... No change at all. So I checked the input side of the fuel filter and I have no fuel pressure. So I start by checking all of my fuses and relays. All seem to be good. I then check to see if I have power at the connector at the fuel pump and I do. So I order a new fuel pump. Install and crank..... No change. So now about $1300 in on this repair and still no running car. I then pull the the rug to check the diagnostics on the ecu. Turn the key to ACC and no LED on the ECU. I pull the plug on the ECU and have power on pins 49 58 and 59...but no LED. I try resetting and removing the Anti theft to see if that is the cause but no change in the symptoms. Please help before my wife leaves me lol.... but seriously I really need this car to be running soon before my wife's classes start back up.

instead of guessing and throwing parts at the problem you need to do serious data gathering. Fuel Pressure by gage on the ring ( not I think it working)? Intake clear. Exhaust Clear. Timing belt still in one piece? Are you getting spark?
