I've got a '94 5.0L EFI. First thing in the morning, she fires right up. After that, you have to play with the pedal to get it to start. Iv replaced coil, cap, wires, rotor, plugs, IAC, throttle body, MAF. Iv adjusted the idle screw trying to help it. When i do get it started it smells straight like fuel is dumping straight out of the exhaust. I have noticed that if i crawl into it, and turn the key on and let it sit for a few seconds, its easier to start but its not a smooth start. Anyone got any ideas? Iv been told the regulator is not holding the fuel up in the rail and was wondering what yall think.
