Re: 2001 ford f150 4x4 5.4 problems
Take a flashlight and look at the fuel rail are any leaks observed. Look for a vacuum line going to a pressure regulator on the rail. Pull the vacuum line if any gas is observed replace the regulator. I looked at a couple of regulators.
Vin L was $76.00 and the other one was $1276.00 hopefully you have the cheap one. This is a picture of a fuel pressure tester. http://www.autopart.com/tools/toolsmain/tool/T_3440.htm Look for any gas leakage along any fuel lines put it on jack stands and look carefully. You may need to check the vacuum canister. Auto Zone and Advance Auto will scan the engine for codes free. Repost any codes.
