Codes p1642 and P1646
Good afternoon, I have a 02 XJR with codes read from a obdII scanner that come up as P1642 and P1646. The code P1646 is for the fuel pump relay from what I gather. The car itself seems to run okay beyond the fact the gas mileage has gone done a couple of miles per Gallon. Any help would be greatly appreaciated.

Did a quick search for you, here is what came up. Check out all threads, even just briefly...and the XK8/XKR shares the same engine, so you'll find some good info there also.
