My '96 4.0 has become reluctant to start first time of the day. Today I uncapped the Shraeder valve on the fuel rail before turning the key, and nothing came out. I then primed the pump a few times, and got a good spray out of it. (Our other '96, sitting since Saturday, still had good pressure at the rail). Then, I tried to start it, and it cranked a little, and fired up just fine. It starts and runs fine the rest of the day.
Do these fuel systems have a check valve involved also, and is it replaceable? The pump still sounds strong when primed, but loses pressure overnight.
