I agree that it sounds fuel related if you are getting low pressure. However, have you checked what your spark plugs look like? Perhaps you have some leaking VCGs and may fouling the plugs. I have had it happen to me which is the only reason I would tell you to check the plug condition.

Well, all the gaskets above the h/gs are less than a year old, including the valley pan gaskets. The x never misfired once, before that day and doesn't burn any oil. Also, the low rail pressure pretty much rules out anything in the ignition system. I didn't mention this, but there's no cel lit.

Sounds like bad fuel pump. My wife's 325i did the same thing.

Update: I changed the fuel filter yesterday, but the battery went dead from sitting, so I couldn't see if that solved the issue. I'll be charging the battery and trying to start it, later today(fingers crossed).

Update: the x wouldn't run unless I had my foot to the floor and even then, it was barely idling. Rail pressure check returned a 12 psi reading, so with the filter/regulator out of the equation(it was the original and needed changing anyway) I'm moving on to the fuel pump. There's no fuel leaking anywhere, so the fuel pump must be giving up the ghost. Unless I've forgotten something major, there isn't any other component in the fuel system, that would cause a low-pressure condition at the rail.

You could have a bad transfer pump and even though the gauge register 1/4 tank, the fuel pump pickup side could be dry. Try dumping a couple of gallons of gas into the X and see what type of fuel pressure you have with key on. If this solve your problem you have a bad transfer pump.

Noted. I ordered a new Walbro last night. I figured; if I'm gonna replace it, I might as well upgrade. Will update with results, when it comes in
