Code 2372 -- "Fuel Differential Pressure Above Normal"
Happens when you loose main fuel pressure in the fuel system while trying to drive.
* Bad fuel, clogged fuel filter, Clogged pre-filter, Sucking Air, etc.
* Also can be bad gear pump. <- this is a very common cause of this fault too. Failure of the gear pump is also associated with failure of the electric lift pump. If your electric lift pump is not in good shape, it will destroy the gear pump as it fails, so If your gear pump is bad, replace the electric lift pump along with it as a preventative measure if it is old too.
