2003 Ford expedition 4.6 xtl
My service engine light is on alternator and
fuel pump and battery has all been changed,
but now when I back up to park it will just
cut off it will also just cut off soon as I cut it
on even if I let it run for a little bit, so I don't
know what to do because I don't know why
it's cut off .
You need to take your vehicle to a parts store like autozone who will read the check engine light for free then you will know what is causing your problem instead of throwing parts at it guessing.
