I'll tap test it before I try one of the two $20 MAFs I carry as emergency spares.

If/when I find an extension hose for my pressure tester, and see that the pressure is dropping on turns, how does that reconcile with running rich all the time, now?
Does anyone know where to buy a 3-ft fuel pressure tester hose extension?....
Haven't felt good enough for a few days, with rotator cuff tendonitis and some sort of cold (my Grand-nephew caught Typus, but I suspect that I haven't, separated by 100 miles and 3 months from contact), so after receiving fuel hose parts (5 ft hose, small clamps, and barbed union reducers) I hooked it up to my fuel rail, and taped the gauge to the windshield.

First, I did the tap test, with no change, and then reset the faults stored, MAF voltage fault + P0172 and P0175 (rich codes, on my Torque app), then checked my rigged-up my pieced-together fuel pressure tester extension hose for leaks, and went in the house to get my wallet.

Upon returning, I turned the key, and no crank! I checked for new codes, and found no faults. Battery is sitting at 12.7v, so that shouldn't be a problem, but I'm going to hook-up my 20amp stable power supply/battery maintainer and let it charge for awhile, before I try anything else. I didn't rest codes with engine running, but did the tap test and fuel pressure leak test with it running, at 14v. Did my EWS lose its' place again, like it did a year ago when I changed batteries?

WTF is going on with my X5?
