Can you retrieve the trouble code from your computer? If so, this will narrow down the problem. Are you sure you are not out of fuel? Not sure what the pancake contraption is in less it is the fuel back pressure regulator. The regulator restricts the amount of fuel returning to the gas tank, forcing more fuel to the injectors, thus making more fuel inter the cylinder to make it go faster. I suggest going to your local automotive parts store and pick up a Chilton (or equivalent) manual #266664 which covers 1987-1996 Ford Pickups. This manual will help you alot and only costs around $20.00. What engine do you have? Is there a vacuum line going to the pancake thing and is it hooked up and in good condition? Check all of your vacuum lines and wire connections before doing any repair work.

Mike,
my truck does have 300 6cyl motor with duel tanks and the metal contraption does not have a vacuum line to it and it looks like that i would have to replace the gas line with it.
Thanks Troy

Check the collision switch inside the cab on the firewall above your left foot. Reset button on top of it. Or relay may be on left finder well under hood.

The relay is usually green in color on the drivers side engine compartment. The inertia switch or what the other person described as a collision switch can be located in 3 different areas; left kick pannel, right kick pannel, and on firewall inside cab on either passenger or drivers side. If there is no power going to the inertia switch with key on. it will be your ignition switch or fuel relay. Common issue is the fuel relay because it is mounted upside down and will collect moisture.

1990 F150 4.9 EFI. Fuel pump runs for as long as a minute. It will then start, and with the exception of an occasional high speed miss, it runs ok. Same process to start it again. Found a loose, capped hose that was clipped to the frame in front of tank. Dont know where it goes. Could it be check valve or something else?
