I've got a 2005 Dodge Ram 3500. There is no error codes presently and rail pressure is a max of roughly 5,000 psi and at idle its start to surge dropping as low as 1,900 PSI on the rail. I know this is not enough rail pressure at all for normal operation. I've changed the FCA without any change in pressure or operation.
