Car turned off while driving 40 mph on the road. Car will now crank but won't start. New starter, new fuel pump. What to check next??

D3 is not a code. Key lit up on dashboard indicates some kind of immobilizer issue. However, the immobilizer system will prevent the starter from cranking if a key is faulty. I'd honestly be looking at engine timing and compression. Depending on oil changes and usage, I've seen some timing chains stretch and jump time. Just a guess but can be certainly a cause of stall and no start. Hands on testing, regardless, is needed.
