Car cranks but does not start , sometimes it wants to start for like 1/2 of second and it dies out right before it stops cranking . Need someone to shine some light on this . Thank you in advance . Regulators show 55psi when cranking .

Those codes point to a fuel delivery problem. A quick google search, generic OBD P0627 is an open circuit to the fuel pump. I think the rest are low fuel pressure in the rail. P0171 is a lean code.

1st is visual inspection of all the connectors on the wiring harness that have to do with squirting dino-juice into the cylinders. From the main fuse block to the engine back to the fuel pump. You'll need a wiring diagram.

Or you can parts-cannon it, and stick a fuel pump in it.

Do you hear the system priming? I'm having a similar issue thinking I have a bad fuse or relay because it affects both my fuel pumps

When I open the door sometime I do hear the pumps turn on . But sometimes I don’t hear them at all
