I am officially stuck 
I've got a 98 Cobra that I recently built an engine over the winter. The full details can be found in my build thread on here, but a quick recap:
98 Cobra
-4.6 4v Teksid block with forged bottom end
-DB Casting C heads with 98 Cobra Cams
-Mach 1 Intake manifold with adapter plate running stock upper lid and stock TB
-COP swap (went back to stock coils and plug wires to eliminate the COP's. Zero difference going back to plug wires)
-Fore fuel rails with Fore FPR
-JLT CAI with stock MAF (and SCT BA 5000 MAF, I've tried both)
That's all I can think of at the moment.
What the car is doing:
-I did break the clock spring and have an airbag light (new one is enroute). Because of this car would initially not start. Just cranked and cranked. Tuner sent me a revised tune file with the PATS turned off and the car will now do what I have typed below
-Will crank and lightly hit but won't start 9 out of 10 times
-Every great once in a while the car will hit, start, rev up to 3k (sounds amazing) but then immediately dies. This makes me think there's no mechanical issue with cam timing, etc (had all brand new OEM timing components installed by a very well-known, pro local engine builder that has done a ton of these)
-I, at one point, was able to get the car running with the MAF unplugged for about a minute, but it eventually died
-Plugs are covered in fuel. They were brand new.
-White smoke coming out of tailpipe after cranking car that overwhelmingly smells of fuel. Car will backfire loudly every now and then like there's a ton of unburnt fuel in the exhaust that ignites
-I have the battery ground cable going down to the driver motor mount stud and then from there to the brake line bracket on the driver side. Verified with a multimeter that I have .9-1.2 ohms when I touch the alternator housing and the battery ground pole
The car ran and drove before I did the built motor over the winter. It was down on power, but it ran and idled. Has a brand new 255lph stock style (funky 98) fuel pump and new fuel filter.
I have to be missing something. What should the vacuum lines look like? What should the grounds look like? Any other suggestions?
