I have a ford f150 2005 5.4l last week i took it to the mechanic for the check ingine light that was on n when i got there the mechanig changed a fuse cause his computer was not reading anything cause my truck had that fuse burned so suddenly since that moment my truck didnt want to start so they told me that probably had a bad fuel pump so i took my truck to another mechanic cause they dont do those things so when i got to the other mechanic they told me that they was gonna check the fuel pump n they checked it n that fuel pump was not the problem n the kept checking n checking n they couldn't find anything i told them to change the fuel pump driver module n they did it but still my truck doesnt want to start idk if is an electrical problem or something else n i cant find the fuel switch that cuts off the fuel on this truck does anybody knows something about all this that can help me to fix my truck?

 

Ajtilo, I moved your post here, and deleted the other two identical posts. Please don't create multiple posts on the same subject. It just causes confusion.

Post the check engine codes that the mechanic read.

 

Check the wire harness under the drivers door. If the loom wrap is torn up by rocks there is a good chance you have a bad wire in there. Seen it many times.
