So I have a 2005 mustang gt 4.6 3 valve. My fpdc is reading 0.50 steady! Doesn’t move. At idle or WOT. So I’m assuming that my pump is running at 100% all the time correct? Because I have nothing after 4700 rpm!! I’m using a sct x4 tuner. Am I reading this correctly? If so I need a new pump asap. Someone please help.And just how does one do this? My Predator can only datalog certain parameters and pump voltage, and lookup table voltage are not on the list.
