Just check the Alternator still good and charging battery 11.6v
Battery measure at 12.6v
Compression on all Cylinder is within spec at 135 PSI

Check all the relay and Fuses non blown or damage

What is the fuel pressure? the fuel pump working only tells you if the in-tank fuel pump is working, but what about the HPFP? What's the pressure? Insufficient pressure from a working fuel pump will cause the car to stall out.

How exactly are you measuring 11.6 from the alternator if it won't start?
