Okay! I am getting somewhere. First, you cannot use a tire gauge to check the pressure at the fuel rail. The needle valve on the rail is too deep for a tire gauge to reach.
Help me figure out which pump is bad. I turned the key on and primed up the gas rail. I took a small screw driver and pushed in the needle valve on the rail. Their was only about 1 pound of pressure. The gas did not spray it just barrly came out over the top.
So I started my Bronco and pushed the needle valve again while it was running. It sprayed this time but very weak, it maybe shot up about 8 inches but did not have strong pressue. How should I determin which fuel pump is dying?
