I have replaced the fuel pump amongst a lot of other things. I can spray gas or starting fluid in the throtal body and it will run rough untill the fumes ware out. Its a 1995 ford explorer 4x4 xlt
If you hear the fuelpump operate the first 1 or 2 seconds when the key is turned to RUN position, the fuelpump is working. If you do not hear the fuelpump run, check the Inertia switch which should be in the side panel of the rear cargo area. If you have an owners manual check for the Inertia switch location.
To reset the Inertia switch, hold the button on it for 2-3 seconds. You should now hear the pump run. You may also have a fuelpump relay under the hood in one of the Powerboxes. The Powerbox may have a fusible link from the Battery. When the fusible link is OK and the Pump Relay is OK, there is a fuse in the Fuse panel. Then finally the Ignition switch will trip the Pump relay. As power flows through the wire to the fuelpump the Inertia switch can break the power connection.
So you have 5 powerpoints before the fuelpump will work. Fusible link, Pump Relay, Fuse Panel, Ignition Switch,and Inertia switch. These must all work before the fuelpump can run.
