Have you tried replacing the starter? I know starters can go bad if the car is not started or run for a long time.
I am getting the same car, with the same issue.. it sat for 2 yrs and won't start.
My mechanic told me it is probably a starter.

i actually have a 1985 302 efi... there are 2 pumps one one the rail right under drivers door and one in the tank.. there are also two filters... one just behind the pump one the rail.. its actually inside a canister that you open with a oil filter wrench then it has a paper element inside..then there is a inline filter that is actually part of the high pressure line the hose is about 3 feet long and runs from your front pump up to the fuel rail agaist the firewall...this one is really hard to find (Buy) good luck wish i hade a carb

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.

Same problem with my 85 F-150 5.0 EFI---turned out that the fuel pump relay under the hood was teriffically corroded on the inside (I opened up the relay to look inside). When I checked the voltage at the fuel pump it would show 3.5-6 volts instead of 12 volts.
I was thinking fuel blockage or perhaps failure of the in-tank pumps. Sometimes the truck would start and run, othertimes it would neither start nor run. Typically, if running it would stay running until turned off (where the relay had to break).
Changing the green fuel pump relay fixed the problem--12 volts now at the pump and no reoccurance.
Good luck--let me know if this fixed your F-150.

Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.
