This problem is related to the fuel system. You have low pressure. It can be caused by multiple issues: 

Weak fuel pump, clogged filter or screen, restricted fuel supply line Faulty fuel pump driver module Faulty fuel pressure sensor I would do a fuel pressure test. It's very easy and you can do it yourself.

The most common cause of this error code is clogged fuel filter or fuel screen.  Also a bad fuel pump or restriction in the fuel line. Collapsed or kinked fuel line problems restrict fuel flow.
