okay fellas here's the deal: I recently ran out of gas on my dual tank f250. Thinking its just "out of gas" I fill it half way & now it won't start. So I did the obvious from the Haynes manual: change the battery, battery terminals, starter solenoid, plugs, wires ,cap & rotor, ignition control module on the dizzy, fuel pump, fuel pump relay, ignition coil & fuel pressure regulator & air filter. I checked the shrader valve & just little to no gas came out. I'm already $450 into the truck & now running out of leads. I've also checked the inertia switch & resetted it. Could it be the EEC relay? The EEC module? If so, where is it located? Any help will do fellas thanks. I've also checked the threads towards this subject but no avail. It's an 7.5 with a 460 BTW. Please help fellas thanks!

 

Are the fuel pumps turning on for ~1 second when you first turn the key on, and which fuel pump did you change? You have three.

 

You appear to be painfully missing the fuel filter. Is this one of the things changed out?
