And when starting my truck up, I discovered that my front fuel tank pump was not working but the back tank was. After some research I decided to change my fuel tank selector switch on the dash and now none of the pumps will work. This is a dual fuel tank system. I then put the old switch back on and same thing none will work. I have checked my fuses and relay and they appear to be fine. About two years ago I had both pumps replaced and the front tank replaced due to the truck sitting for years after Hurricane Katrina. Any pointers would be great.<\/p>\n<hr \/>\n<p>RESPONSE<\/p>\n<p>I recommend checking the inertia switch first. Should be located under the passenger floor mat toward the top. It is easy to get to and takes only a few seconds to test and or reset. Push the button. Next I would check Fuse O(20A) and then the fuel pump relay.<\/p>\n<h3>Dual Fuel Tank Wiring Diagram 1994 Ford F150<\/h3>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-37579\" src=\"\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2016\/11\/1994-ford-f150-dual-fuel-tank-wiring-diagram.jpg\" alt=\"dual fuel tank wiring diagram 1994 Ford F150\" width=\"870\" height=\"269\" srcset=\"https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2016\/11\/1994-ford-f150-dual-fuel-tank-wiring-diagram.jpg 870w, https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2016\/11\/1994-ford-f150-dual-fuel-tank-wiring-diagram-300x93.jpg 300w, https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2016\/11\/1994-ford-f150-dual-fuel-tank-wiring-diagram-768x237.jpg 768w\" sizes=\"(max-width: 870px) 100vw, 870px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I just replaced my neutral safety switch and starter solenoid starter switch.
