Thanks whit, told him your suggestions
Just could call him and he sent me emails:
Well I think I finally found the problem. One more 5:00 am morning checking things before work!!
After checking and swapping MAF's, DME's, DME relays, I made a breakthrough discovery, My car was in a sort of Limp Mode. I crawlled under the car to check the CATS and noticed that the one side was cold to touch. Thinking spark or fuel issues I checked the fuel pump relays, coil, induction test on the plugs, vacuum lines, fuses - all checked ok. After recieving an idea from Shogun and Harywithit I was heading to Johan's site for the fuel pressure regulator change. Part way through it details jumping the fuel pump relays to check for fuel quantities. Sure enough, the side that wasn't working wasn't receiving any gas!
All I can think of is in the morning I'll check the connector at the tank to ensure everything is good to that point, before coughing up $200 or so for a new fuel pump.
Having said all this and seeing the light at the end of the tunnel, does anyone have any other ideas in case this doesn't pan out?

That is the status as of now.
If any ideas/proposals, just me me know.
I am checking now for a used pump in Japan. Or does anybody know what other maker than Bosch can be used. BMW p/n for the pump only is 16141179710.
Bosch p/n (not sure) is E300-150664
Regular price is $ 306,-, so it will cost here in Japan abt. double that price.
Checked various online vendors in USA like expressautoparts.com, autopartswarehouse.com, prices 237,22 and 215,47.
But there is a pump at bavauto.com with their p/n GFP316 which costs $ 199,95.
That seems to be not a Bosch pump. Does anybody know the maker of another brand for this pump and/or the specification/size etc. for the pump? Maybe they are also available in other japanese cars, so then we could get a pump much quicker and probably cheaper herre in Japan.
Thanks
New update since last post (from Real)
Well I thought it was the fuel pump and it still maybe. I was pressed for time so I went ahead and installed it without checking if there was fuel between the pump and the fuel filters. I checked at the engine and I still do not have any fuel to the left bank (7-12 cyls?).
Jim and others mentioned "Limp Mode" is there a way that the engine can go into limp mode and not display an EML or other warning? As I stated in a previous post I have swapped MAF, DME, DME Relays, Fuel pump relays, inductve spark check on both sides. The problem remains on the left side.
The only other thing I can think about is that I will rout a piece of hose from the sending unit to a bucket to see if I have fuel there, if so, I'll check the fuel filters. I doubt that if it is a fuel filter issue that it would have clogged so abruptly (working in the morning and not in the afternoon). Any ideas on this. If there is fuel at the sending unit the only thing between there and the engine bay is the fuel filters right?
Shogun has asked about the EML. Prior to start up it lights for a couple seconds and then shuts off.
Does anyone know of any other reason why fuel is not making its way to the engine?
Still plugging away at this, hopefully it will be solved soon.
---------------------------------
I tested the fuel pmup in the engine bay as described in the previous post. At that time I checked the fuses again and noticed that since I installed the new pump my fuse #24 (fuel pump) was blown. I changed it out with a new one had then had my wife check the car after starting it. That same fuse is burnt out again. Is it possible knowing what I know now that the fuel filter may be pugged solid not allowing any gas to go through, in turn causing the pump to over work and blow the fuse?
