I have a 2010 F450 6.4 with intermittent P0088 Fuel pressure high code and limp mode, I read a lot of them having faulty pumps and need replacing but also saw a post about a Ford software update to rectify it. I was looking for a stock file to see if mine has been modified and also does anyone know if the file attached is old software that needs updating or if it has P0088 fix?
Thanks
You?re best bet is to datalog the actual pressure and duty cycle to determine if you?re losing pressure. Failed pumps many times take out injectors so be forewarned.
