Thanks for that. It is making a little bit more sense now. So the pump running is normal all the time. I think you are right that maybe the relief valve may be stuck. Is it part of the pump itself...? Still I will check fuel pressure to determine if electrical reading is the same.
Does the tank have to come out to access fuel pump or is there access through the floor somewhere..?
I will try and get a picture of where everything is....thanks again for your input.
