My truck had this problem. Change the oil pressure sensor and see if it solves the problem.
I have a problem that I can't find out what it is.
Mid128 pid94 fmi 7
I changed almost every part in relation to fuel and the truck still tells me fuel feed pressure low and refuses to start -
Oil pressure sensor, oil temp. sensor and EGR valve #1/#2 all share 5v reference. 9 times out of 10 one of the EGR valve harness has rubbed and is grounding because they are so long. Usual spot is where they cross over front of engine from passenger side to driver side.

Sounds like fuel pump failure. It is a common D12 issue. Fuel pump and accessory drive should (must) be replaced as a pair.

Thanks a lot. I changed the pump only but not the accesory drive. I would change it and see if it solves my problem. Thanks
