F250 Heavy Duty Pickup. I have checked fuses and fuel relay, both are working. I also replaced the fuel filter. Truck was running fine. Stopped at the store. Truck would not start. I switched to the rear tank. Truck still did not start. Waited 5 min. Switched to the Front tank. Truck started. As I was driving I switched to the rear tank. Truck began to stall. I switched back to the front tank truck continued to run. Stopped at gas station and filled up the front tank. Truck would not start back up. Had to be towed home. Any suggestions will be welcome.

Greetings,
I view your post with compassion! I have a '92 F-250 and just had the fore tank fuel pump fail. You do not mention the year of your vehicle but, of course, fuel pumps to fail and can do so initially in an intermittent fashion. Are you sure you've "no power" to the fuel pump/sending unit connectors? I've learned that these fuel pumps lubricate via the actual fuel in the tank and it is NOT good to run them dry as it accelerates their demise. Replacing the pumps is a major repair thrash as the tanks have to be drained and dropped, the locking cap removed and the pump withdrawn and replaced. But perhaps you do, in fact, have an electrical problem. Let me know how you do. . .
