I have a 2000 GTX DI with low fuel pressure. Original OEM pump, new filters, cleaned in tolulol. Air pressure is 78psi and holds steady when I supply air with an external compressor. Air compressor puts out over 110psi when dead head. So I am looking at either the fuel pump or the fuel pressure regulator. I get 27 psi exactly when I insert the key. When I have the air side at 78 psi, the fuel side goes to 60 and just sits there, steady as can be.
How would I confirm which part is bad - the pump or regulator? From taking apart the fuel rail, I believe I should only be getting fuel recirculated back to the tank after the regulator releases - is that correct? So if I see 60 psi and fuel coming back to the tank, that means the regulator is bad (releasing too early)??
I am so close to getting this thing running again and believe this is my last hurdle!
