2004 f-150 fuel pump plug
 

while removing fuel tank 2004 F-150 we unhooked the main fuel pump connector and also needed to unplug a square plug about 4 inches from the main plug. reinstalled tank and now have crank but no start condition. How do I correct this situation?

Are you talking about the Fuel Pump Driver Module mounted to the frame rail above the spare tire ?

How much gas did you put back in? This happened to a buddy of mine and since he had the truck jacked up from the side he just needed more fuel.
