We're is fuel pump Fuze on 2004 F150 - F-150 Ford Cars & Trucks

Its not a fuse it is a relay and should be located in your power distribution box under the hood on the driver side of the vehicle. do yourself a big favor pull the tail connector that comes from the top of your fuel tank get a simple test light and test the wires on the plug before the tank have someone turn the key off and on check the wires while they do this usually turn key on it will run 4 a few seconds giving time 4 you to check for power to the tank if you indeed have power going to the tank replace the pump the relay is not your problem if you do not have power going to the tank the relay might be your problem I have also found the key or key switch is malfunctioning and causing the problem. Note if the pump is bad make sure you replace the sock on the pump one little grain of sand will lock the new pump up tight and all the work to replace it will be for nothing make sure to purchase a good pump from a decent parts house like Oreillys and replace the pump sock and a new fuel filter and keep the filter changed at least every 8 thousand miles. failure to do so will cost you plenty in the long run.

Fuse #34 serves the pump, injectors and power train control module . Ford had trouble with the fuel pump driver modules corroding on these as well . They are located above the spare tire and cause no fuel pump activation issues .
