Hi there.Sounds like the fuel pressure regulator is failing. Check fuel pressure first thing in the morning when the engine is cold; pressure should rise immediately to 45-49 psi, then not fall below 30 psi for at least another 5 minutes. If the fuel pressure regulator needs to be replaced, it is recommended that the fuel pump module be replaced - complete module costs about the same as the regulator.
