AHHH, Finally its FIXED!! It was the power connector to the fuel pump was busted, so it would not stay on the prongs. The "fuel cut" i was experiencing was the connector going from making contact to not and would kill the pump and come back on. Wow am I glad thats fixed now to find a new plug somewhere. Thanks to everyone for the input!!

So this is odd, car is running and has 0 PSI... anybody? Im stumped, only thing I can think of is stuck open fuel injector. Exhaust is strong and squirts out fuel..

Alright I'll look at the relay, it has the same exact one for the fuel pump and the o2 heater. I tested resistance on pins 86 and 85 they were both 84.8 ohms so idk if that's good or what. But like I said I have a clear tube off the T and you can see fuel as it cranks and barely goes up the tube like its using the oil pressure to pump fuel. But in the video it has a constant 30 psi but when you give it gas it just drops out to to zero if you keep on the throttle..

So I put a fuel pressure gauge on it.. So when i turn the car over its not pumping fuel very fast i have a clear line off the T valve thats on the fuel line, so I can actually see the fuel coming up the line takes about 15-20 cranks for fuel to reach gauge. Will start after that. idles perfect at about 32 psi now when I go to drive it this is what happens. Car at this point is at running temp ~175-180 im in second gear( does not matter does it in all gears, even neutral, psi drops faster with a load on it) cruising at 2K rpms fuel pressure is ~30 the more gas you give it the faster the psi drops until it is at 0 and has no spark you can pump the the pedal and have no response. But if you let off the gas the pressure jumps back up to ~30 psi.. So basically its when you give it gas that the PSI will fall to 0... Any thing I can check? fuel pump is about 5 months old, same with filter I replaced them at the same time.

HERE is a video, kinda crappy sound due to my Lifeproof case.

As you will see when fuel pressure is at 30 im barley on the gas ( more so momentum than throttle) as you see it drop I am giving it a range from 50-100% throttle, basically the more you give it the faster it drops to 0 and has no spark. Let off throttle goes back up to 30 psi..Thanks for looking!

Also forgot to mention, the car has about 5 stripped out bolts on the VCG, was reading some info that it could cause  PCV vacuum leak, causing it to fail, thus throwing a CEL for o2 sensor because it allows to much air in and dilutes the AFR causing it to run rich in conclusion it runs like shit and throws a 1221 code..All started couple months after the VCG bolts were stripped. Here is the link. Thanks

I've read a few instances where people were getting bad aftermarket sensors. Might be best to bite the bullet and pay for BMW parts in this case.

Yeah same here, its about 120$ for a Bosch so thats what we are going to do. It must be a hot item, only place i could find one was turner and bavauto. Pelican is out of stock like most other places.

Okay well we did the testing, Cam sensor was 1200, and crank sensor was 510. I read A few threads, its saying that its +/- 10% which would be like 580-700 range. So I think were going to order one and see what happens. Because 70 OHMS under the minimum is a lot.
