Truck has been hard to start when warm for about 2 yrs now, but yesterday when shifting from 3rd to 4th it just died. I had fuel pressure and still get 18 psi when cranking, but no fire. Did key on/off thing and got p 1693. I think vp44 just took a dirt nap!! The truck has 116k on it and as far as I know it is the orignal pump. If it is the pump, who's should I go with (II's hrvp44)? Thanks
