hello all... got another fun issue with my 2014 mustang 2100rt engine
machine has 2500 hrs .
has the yammer 4tn98
machine is throwing code for low fuel rail pressure 157-18 dealers have no idea, local yammer shop has given up...
has new injectors, new injection pump, new filters, new fuel lines, new lift pump,
im going in circles..
if I pull fuel pressure valve out of common rail and rev engine to full throttle I've got gallons of fuel dumping out of the pressure regulator valve.. is this normal? tried to swap with a spare I had out of a common rail cummins "same Bosch design" with no change...
any experts out there have any clues. thanks
