Hello P0251 is a difficult code to diagnose as it can cover injectors, fuel pump, imv and the fuel pressureas you also have P1211 then you need to do a leak-off test. As the P1211ndicates that the main pump can't generate enough pressure but the most common cause of this is that one or more of your injectors are leaking too much fuel away how to perform a leak off / run back test is detailed here: http://www.talkford.com/community/page/fordwiki/fordwiki.html/_/mondeo/mondeo-mk3/injector-leak-off-test-r121
