Did Fuel Pressure test with borrowed Inova Electronics Fuel Injection Pressure Tester. Relieved overnight pressure (there was some), hooked up gauge, key on - instant pressure to 41 psi.I Bled fuel off. Then key on - same psi, key on -start- hard to start,cranked for 4 sec.- stop- crank for 3 sec- weakly started engine, but fuel pressure went up to 48 psi. Held steady-no gauge fluctuation. I never touched throttle. Idle has always seemed low on this vehicle, even when very cold ambient
temp. (20 degr. winter morns.) Engine slowly levelled out to decent idle, but fuel press. never varied. My Haynes manual says 39-41 psi. Can't disconnect press.
regulator or check it- it's in the tank with fuel pump. Is pressure too high? Do I have a faulty pressure regulator? I really don't want to endure a fuel tank removal, especially since I just filled up my 30 gal. tank. Any ideas?
