Ok so I ran through the crank no start checklist here are the results:
1. Not sure how to do since it's distributor-less
2. Sparks at plugs
3. Doesn't start with starting fluid/pump primes, inertia not tripped
4. Getting 25psi key on engine off post prime/no black smoke, getting wispy white/gray smoke (hard to tell) from the tailpipe
5. All injectors firing/TPS test good
6A. Can't set the idle screw until I can start the engine according to
http://mustangspecialties.net/mustang-idle-set-up.html but I can't get the engine to start no matter where the throttle is held
6B. Haven't cracked the ecc open in about a month but the last time I did it looked fine
6C. Timing good as far as I can tell
6D. Firing order/spark wires correct
6E. Can't even get it to start cold
6F. Last compression test was good less than 6% difference, all cylinders around 140psi
No new codes
I will crack the ecc open tomorrow and inspect it again/post pics. I will try and get another compression test as well if I have the time. I'm truly stumped on why this thing doesn't want to start. Lol this car is officially the biggest pain in my @$$ I've ever had to deal with but I can't bring myself to give up on it. Only vehicle I haven't been able to bring back to life yet.
