Running premium fuel? DTC P0089?
Suggest starting with replacing the fuel rail mounted pressure sensor (pn 12582232). If that doesn't fix your P0089 then replace the fuel pump assembly (same expense but much more labor than sensor replacement).
As Chadwick says, be sure to check all cylinder compression numbers when plugs are out. Have now seen three 2.8 v6 Aeros lose almost all compression in one cylinder from hammered out valve(s) which require engine R&R to pull and replace the cylinder head.
