Sorry to hear about the issues you’re having with your truck, but we’re more than happy to help! The fuel pump relay for your 2005 Ford F-350 is located in the passenger cabin fuse box on the driver’s side under the dash. The fuse you need should be in slot number 40, but double-check your owner’s manual and/or the diagram on the panel cover to make sure.
Stalling is a common symptom of a faulty fuel pump relay, so hopefully, this quick and cheap fix will take care of your issue. If not, you may want to head to a garage to get an expert’s help. It may take some time and cost a bit more money, but an expert can make sure all of your truck’s systems are working properly.
