Fuel pump fuse location

I lost power to my fuel pump and I was told that somewhere there is a fuse or fuseable link somewhere leading to the fuel pump. If anyone can lead me in the right direction, I would greatly appreciate it!

Pickup is an '02 XLT ext. cab 2wd with the 4.0 engine.

I believe it runs off a fuseable relay. its a 20amp relay (for my truck) and its in the fusebox under the hood, driver side near firewall, next to brake booster, and brake fluid resevoir.

my owners manual shows it to be number 9. Open your fuse box lid, itll be the by itself, closest to the firewall.

pull the relay out and look at the prongs. if they are burnt and/or you smell burnt metal/plastic inside the relay then its probably toast. theyre cheap to replace

Well, I replaced my filter yesterday since that was easy enough to do and moved some relays around to see if it would fire up but still nothing; it cranks only. I was told there may be a fusible like somewhere that could have gone bad but I have not idea where it is. All my fuses are good, both inside the dash and under the hood. The check engine light does come on so I know it is not my PCM. I may get a fuel pressure tester just to see if there is any pressure. I was also told that if the engine does crank over that it is not the ignition switch and is more than likely either the pump itself or a fusible link leading to it.

I was also wondering about how heavy the bed of the pickup weighs since I will probably pulling that off soon. It is your average 6' fleetside.

Was this determined using a voltmeter? If you stand outside the vehicle, with the open drivers door, stick the key in it, reach in and turn the key to run (don't crank it), can you hear the fuel pump run for maybe half of a second as it builds pressure?

Thoughts:

Did you firmly press the red button on the inertia sensor to do a reset, if that was needed?

Do you have a voltmeter to check for voltages? Or even a basic test light to check for voltage?

If so, did you check both sides of the fuse for voltage?

I don't have a wiring diagram for an 02, but I do know that autozone has (had?) freebie repair manuals online. They can be limited as far as what they provide for info, but still, maybe worth looking for a schematic there. A good one, like the factory wiring diagrams, shows the location of connectors which would be useful to know as you're tracking voltage.

Not sure if there's a dedicated (<<keyword) fuseable link for the FP, but it would not be logical to design it this way (PITA to repair). My handful of experiences with fuseable links is that the downstream wiring/items protected by them are several and not a onezy.

Ok, I got the pickup back on the road after I determined it was my fuel pump and replacing it and I just wanted to thank all that responded and for this forum as it does help as right now I do not make alot of money but save the labor charges by doing it myself.

I checked the fuel pressure at the schrader valve on the fuel rail and although I had fuel up there, the pressure was like <5 so I knew it was the end of the life for my pump. I took others advice and took the bed off which makes the job SOOOOOOOOOO much easier! When I was disconnecting the fuel lines, I broke one of the plastic clips that hold it on and then remembered that someone else had this problem and he used a zip tie so I did this as well.

Again, I just want to thank all who responded and also for this site!
