po313 code fuel pump

Last night I fond a new code to add to my code list on this BMW 530i.
It was the po313 misfire with low fuel. I had the po174-171 code for about two weeks now.
Have had the throttle body and manifold gaskets replaced. Check the rubber tubes from thee MAF Had a smoke test run and that built up a slite pressure. It is cold 15* and the engine started to run poorly and misfire when changing to FOl-run to c1osed loop, run on 2-4cyl no power when accelerating jumps when let off gas. Got home 1/4 mile parked it now I will wait to see Think all the past problems have bin the I have a failing fuel pump. I have replaced the fuel fiter twice. also had all the cyl report a misfire.


Completed referb of interior now like new+some extras not offered. TK

Don't know yet. Will check tomorrow. Should be 35psi for 2001 or 75psi for newer model?

what was the fuel pressure reading? low pressure can show as the lean mixture codes youre getting.
