![]() ![]() ![]() I only say this because this seems to be a well known issue with this particular year and model of F150 I have no doubts that a bigger surface and connector area of a maxi fuse would have prevented this problem. Of course the pump could be drawing more amps at it's age of just 220+k miles, and one would have thought a maxi fuse would have been used on such a circuit, however given the fact it is the fuel pump, it's possible they were just being abundantly cautious. Reading up on the issue I gather that Fords has made a fuse relocation kit for this in the instance it melts all the way down and the contacts are missing.įrom my years of experience, I would imagine the load of this circuit (fuel pump) is such that the heat and such relative small size of these newer maxi fuses and their contacts, that over time it just melts them away from the heat. Upon replacing fuse #27 in the engine compartment fuse box (just above the radiator) the truck runs fine now. Come to find out fuse number #27 was burn up, looked like prolonged exposure to heat. ![]() Had customer get towed in today on a no-start 2010 F150 4X4 with the 5.4 liter engine. ![]()
