What is the fuel pressure for a 5.4 L ford expedition engine
I have a 2008 Ford Expedition and I am having problems with the engine after changing the spark plugs and fuel filter, I think the fuel pressure is too high, 60 before start and above 70 engine running. Is this normal? I can smell gas on the exhaust now. No check engine and verified the spark plugs twice.
Yes, that is high. Might need a fuel pressure regulator, or Ford calls them modulators. Specs for the 5.4 are 35 psi +/- 5
Do you know where is the fuel pressure regulator located on the truck?
35 psi +/-. You are way too high.
