It's an OEM crank sensor. Foots not on brake. No error codes.

I picked up a fuel pressure gauge and pressure was 80psi when car on, holds at 50 with it off. Other car was 50 across on or off.

Fuel filter was new from mechanic and fuel pump is new by me, tried the two fuel pumps.

Maybe it's a bad fuel pressure regulator on the fuel filter.
