It looks to be moving a bit, but one interesting thing I noticed,- when I press release knob, there is no fuel, but just air being released. Tried it several times,- same results... As if fuel doesn't even get to the engine. One mechanic mentioned to me that you can check pressure somewhere closer to the fuel tank... Is that true? Just to eliminate clogged fuel line. After all fuel pump is $300 and it will take time to get it and install. Wanted to make sure that this is the cause of my issue. Once again - thank you guys for your advise and help!!!

Like upallnight mentioned, look at the thread where I had my issue. Basically what you are looking for is for any pressure in the line. If you turn the key, the pressure I believe should be in the ~35psi range, and running around ~50psi range. If it is fluctuating alot, that is a big sign that something is wrong. The release knob (I hope you mean shcraeder valve) should be spewing liquid when pressed if not, then there is air in the line at some point. And a fuel pump on Ebay can go for $100 new, so $300 isn't a price you would need to pay. The fuel pump is easily accessible from the back seat. All you need is some pliers, a good flathead screwdriver with hammer, and a new hose clamp. Literally a 15 minute job if you know what you are doing.
Look closely to the thread
http://www.xoutpost.com/946480-post150.html here. I posted a video of the pressure reading. Mine was a complete Zero, hence a dead fuel pump. When I replaced the pump, it started and ran like a champ. The DISA valve was broken in mine too, so that could cause issues, but I think you need to really take a look at the pressure reading (I don't understand how you did a pressure reading and didn't pay attention to the numbers) and determine if you are getting good pressure. I have since replaced the fuel filter and fuel rail on my vehicle since I broke the schraeder valve (be easy on it) and it was running fine. Can't say that now, but that is another issue altogether.
