Go to Google and enter "2002 Lincoln Navigator fuse10". You will be able to look up everything for the electrical system by selecting the individual pages and clicking them.

What you would want to do is look up all the wiring "paths" to read if a component part may be shorting this fuse. When the individual components are eliminated as problems, then it must be a shorting wire. The plug-in connector for the fuelpump should be clean now, as you just had the fuelpump replaced.

What I would look for as a problem are the other wires going into the Fuelpump Relay. Only 2 wires of the 4 prongs or so will make the pump work. Could be #27 and #34. Look on internet for "jumping the fuelpump relay" on Ford products.

It would help to know if the fuse breaks when the vehicle is off, or when it is running. Reason being that the mentioned fuelpump Relay has 2 or more extra terminals that connect to other devices and they could be tested.

Finally, most people think about a Relay connecting the Positive(hot) wire to transfer power. The fact is, the Negative(neutral) wire is also used to route power and connect the coils inside Relays. When you get a short on a Negative wire, it can falsely activate a Relay coil to connect something. This also means that shutting off the car will not necessarily shut off the power.

SOURCE: E.E.C fuse keeps blowing in 1991 Ford Explorer

if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

SOURCE: no power at fuel pump chev.S-10 looking for fuel pump relay and fuse

The fuel pump relay is located Under hood, driver side, upper firewall, mounted in relay block.

The fuse is located under the instrument panel to the left of the steering column. The fuse block should be visible from underneath the steering column, near the pedal bracket. If the panel is not visible, check for a removable compartment door or trim panel which may be used on later models to hide the block.

Hi Leopoldo

You need to post this in the original post by clicking COMMENT under the person you are replying to. Or if you are just supplying more information, you can click Comment under you own post. Doing it this way won't work as Fixya gets 7 million posts a year, so the chances of the person seeing it as slim to nonexistent.

2002 Lincoln navigator fuel pump relay and fuse location?


The fuel pump relay is 301
the fuel pump fuse is number 10--20 amp. This info is in your owners manual. If you can't read it, try putting your mouse arrow on it and click to enlarge. Sometimes you have to click on your highlited post and go back, may be able to enlarge on that page? Otherwise look at your owners manual. If you don't have an owners manual, fleet.ford.com has owners manuals.

Where to replace the fuel pump relay on a 2003 Lincoln navigator


First check fuse to the fuel pump. The relay may not be a plug-in unit and if truly bad you might need to take it to a dealer. There are several fuse panels - one is in engine compartment and the other is in the passenger side kick panel. I believe the one in the kick panel has the fuel pump fuse. Fuse 1.34 is the fuse for the relay.

Where is Fuse R303 Located on Lincoln Navigator 2003


R303 is the fuel pump relay, not a fuse. The fuse for the fuel pump should be #34. I take it your fuel pump is not working. Check the fuse first. If it's ok then go looking for the relay. It is behind the passenger side kick panel in the fuse box. You will have to remove the fuse box in order to find the relay. It is mounted to the circuit board, and, according to some owners manuals, is only serviceable by the dealer. Hopefully the fuse is not hard to find at the parts stores. If I find out anything else I will let you know.
