Crank no start code 29db

[PupkinRacing]

Long story short, car started to long crank one day. Drive it to work and around town. 3-4 stops long cranked each time: drove it home parked it for 3-4 days, now car just cranks no start. Scanned with protool, replaced crank sensor like suggested. No changes. Threw in known good/used hpfp. No changes. Ground strap is less than a year old. Replaced ekp and confirmed lpfp will prime when commanded to with protool. Kind of stuck on where to go from here.

I believe my problem is a fuel/tune related problem, I did find that people had this issue when their lpfp line broke inside the tank and could not feed the fuel pressure regulator. Also found people who had bad regulators/sending units. One person claimed a crank sensor fixed his issue so that’s what I tried. Replaced the crank sensor and got the car to start eventually. Didn’t work right away. I have a flex fuel tune and need to keep e85 in my tank otherwise my car has issues starting. Thinking something is failing just don’t know what exactly
