Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.
That fuel pressure is too low, I would look at a problem with the fuel pressure regulator, clogged fuel filter, or the fuel pump itself. Low fuel pressure can cause these codes. A vacuum leak can also cause this problem. If the fuel system all checks out, then I would check for a vacuum leak, intake gasket or a crack in a vacuum hose.
