I have 2011 ford f150 that had hard starting during cold conditions. Every time i would start after the first hard start it would crank just fine. Now it doesn't run at all. I checked #27 fuse it looks fine and the fuse box does not look burnt. i swapped the fuel pump relay with another and still no luck. I changed the fuel pump driver module, but at this point my battery has died and is on the charger. Any suggestions would be great. mileage 90,000
