Ford Excursion :: Bad Fuel Pump Relay / Fuse Panel Replacement?
Dec 16, 2016
- Fuse Box - Part # 3C7T-14A067-DC Engineering Number on white label.
- Ford Dealer Part # 3C7Z-14A068-DB
I have a 2004 Ford Excursion 6.8L 4x4 that has a bad fuel pump relay. I am looking for a used replacement fuse panel.
Of all these number and letters which of them tells me the real part number? Does the last two letters mean anything "DC" or "DB"?
So I don't get one for a diesel, what is the prefix for the diesel? I am assuming the 3C7T is gas and the year model?
Also, will this fuse panel interchange with a F250/F350 6.8L or do I need to stick with a fuse panel from an Excursion?

I have a 2013 f150 & the fuel pump relay fuse burnt out. I unhooked the battery cable "wasn't thinking" & took the fuse out & replaced it. Now my truck wont get over 3000 rpms & is driving like i got bad fuel or something. & now its throwing codes about my trac & I don't know why. Just from unhooking the battery cable & hooking it back up. What it is??

Black Beauty finally gave up. Replaced battery, replaced fuel pump relay. Would only run with starter fluid sprayed into the air intake. She'll crank but not start. Here she sits at the dealership.

The fuel gauge sender quit the other day so Im replacing the pump assembly. I believe in replacing fuel and ignition related parts with factory equipment. So I was going to get a Ford Motorcraft pump, but my wife checked for one through her work(local parts store). The counter guy found one that said original equipment, called them and was told "It is the same pump that gets installed on the assembly line". Well it came in today and its a Delphi. I was expecting a Ford pump. I associate Delphi with GM and I know GM pumps go out all the time. I know Ford pumps go out too, but I know several people with GMs that have replaced pumps multiple times within 100000 miles. Is Delphi worth taking a chance on?

I have access to the fuse panel but I need to remove the panel to reach the relays. I need to change the socket in the relay panel because one is burnt out. I change the K(headlight)relay and when my car is off and key out of the ignition my lights are still on.

Well, it's starting to look like I may have to build my underhood harness from bits of multiple harnesses. I found a 2000 Excursion harness, but the engine plugs and wires were hacked off during engine removal.
After in-depth study of wire diagrams, it looks like I can just get a pickup harness and combine it with the aforementioned damaged Excursion harness to get what I need- and do it for about 50 bucks.
I also notice that there are a few Ebay sellers who just sell the fuse/relay box with the wiring harness hacked off of it. So my question is- how do you remove the wires (including the terminal ends) from the fuse/relay box? I've fiddled around with my burned up parts and can't seem to figure it out.

I have a 03 for excursion and I am pretty sure i blew the relay for the fog lights today but looked in the glove box and everywhere for the owners manual and cannot find it anywhere in site... Looking for a diagram or can take a picture of where the fog light relay is and post it on here and which fuse or relay it is ?

I like the looks and ease of adding on circuits. Just haven't found the best place 5 put it. Mounting one of these in the cabin? I want to hook up my mirrors, dash cam, and future add ons without a nasty pile of wires hanging from the original fuse box.

ok, i just became the proud owner of a 71 dodge dart.. fuel pump was not working, and am converting to an electric (airtex e8016s) and am told i need a relay. airtex doesn't seem to have one, is there another i can use? fairly new at this sort of thing, but have fixed a 72 honda motorbike, so not afraid of engines or whatnot.

Well I went to go to home depot and the key turned and my theft light started blinking and I hear a clicking noise coming from my fuse panel. By the way this is on a 2000 7.3l 4x4 limited. I found what was clicking (see picture) it is the second relay down, the one with the chipped plastic. My question is is this a relay I can replace or is it part of the fuse box? Where I can get a replacement? This is my daily driver so I need to fix this ASAP.

Yesterday my wife went out to go somewhere and just got a click when she tried to start the X. I went home and thought it may be a weak battery and charged it up but same thing. The "click" is coming from just behind the fuse panel on the driver's side in the cab. When I turn the key to the ignition position some of the smaller lights on the dash turn off too, like the door ajar light etc, and then when I release the key they turn back on (don't know if that's normal or not, haven't really payed that much attention while starting).

A cousin has an old 1994 Ranger. The fuel pump relay, located in the engine compartment fuse box. went bad, so he got a new relay.
Now, it does not plug in securely, so sometimes he has to open the hood and fuse box and wiggle it to make contact.
Ideally, one would probably replace the fuse box, though that would apparently involve a lot of wiring, right?
How to "cob" this up so the contacts will make better? Perhaps something to put in the slots to increase pressure on the blades?
Maybe gently twist the blades so they go in at an angle? Maybe touch the blades with a solder iron and put on a small blob of solder to make the blade bigger? (Though it seems to me that solder is not a good contact material?
Maybe solder to the blades, a very small piece of brass or similar material? Put a piece of aluminum foil over the blades?

My '94 4.0L XLT has hesitated to start a couple times lately. Then, after sitting for a week while we were on vacation, the truck would not start at all today.

I read about the fuel pump relay, so since I am not made of money, I decided to change that first ($16 vs. $100). After installing the new relay, the truck started! I put the old relay in the box and tossed it into the glove box.
After lunch, and some thought, i decided I wanted to put the old relay back in and see what happened. Guess what! It started with the old relay as well! I also noticed that the humming/buzzing sound the fuel pump makes when the switch is turned on was different with the new relay vs the old one. I put the new relay back in, but now I am unsure where my real problem lies. Intermittent relay, or fuel pump on its way out??

The relay for the fuel pump keeps going bad. Is this a sign my fuel pump is going ? I just replaced my 2nd relay ( lasted about 1 week ) 1st lasted 16 years. Or is there another issue to look at ?

Sometimes after running my 94 Limited, it doesn't want to start - it does crank - like it's not getting fuel. I have found the work around and want to know if it would be fixed by replacing the fuel pump relay.
The symptom is just after starting, it starts to run poorly, and then dies out, then will not start at all. I use to keep trying to start it for 20-40 minutes and suddenly it seemed to work.
It seems the work around is to turn the key to on for about 5 seconds and then turn it off - then it starts and runs as good as ever.
So, is this a symptom of a bad relay? I thought I'd start there because of the cost of the relay is fairly cheap. 1994 Explorer Limited 4x4?

The dashboard on my 01Ex are getting dimmer.......not a good combination but we both have alot of miles on us and stuff just wears out!
In what limited information I can find it looks like I have to pull the dashboard to get to these things. Seems extreme to pull a dash, but then again this is not my 67-Rambler.

2004 super duty crew long bed 2wd, v10 auto SLT.
Manual says not in fuse block.
Looked behind radio, nothing, not even a space or the blue one there.
There are some on the firewall, driver side not marked. No pink wire.
Where else??

My vehicle would not turn over and we could tell it was fuel related. The fiel pump relay has burnt through the motherboard of the fusebox. It is my understanding that this cannot be fixedand another fusebox must be installed. I have been to many junkyards in my are looking for it to avoid the dealer prices..all of the expeditions that we have found locally have already had the fusebox pulled. Any other vehicles that this might be interchangable with? My friend has an 01 expedition..would this work?

I've been driving 93 ranger 3.0 4wd since last fall. first week I went to start and fuel pump relay had blown. I put a new one in and been driving since fine, till today. Now when I try to start, if it starts it will run fine all day as long as you don't turn it off. If you turn it off and restart half the times it will pop relay again. My fuel gauge has been stuck on full since I bought it also. I'm wondering if maybe pump has got had to start and drawing too much current...

1999 f-250 super duty... okay, here is what i have going on. basically no power to the fuel pump. For the last 2 weeks the fuel pump relay and 1 of the relays behind the radio (next to the blue relay) would chatter and the truck would die. Wait about 5 minutes and turn the key on and if the chatter was gone then it would fire up and run... So NOW no chatter on either relay and not cranking up. - motor turns over just fine- just no power to fuel pump. So I changed out the relay- both behind the radio and the one under the hood. still chatters and no start. i have checked the Inertia switch and 12 volts there... Here is my question, when i turn the ignition on, i have no power to the base of the Fuel Pump Relay.... Where does the power come from to power the relay???
