Ford - Ranger :: 1994 - Loose Fuel Pump Relay
Jun 11, 2012
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?

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?

My jimmy died on me yesterday on my way home from work...i thought the fuel pump went because i couldn't hear it when trying to restart... I had about a quarter tank of regular in there,,,put in 2 gallons of super and it started, but died again about a quarter mile down the road...got it home with a push...after searching for and checking any fuses i could find...swapped relays on firewall and all seemed well....i heard the pump and it fired right up...went walked, just in case) and got another relay, and now i don't hear the pump again,the battery is a bit low now,,,so maybe a jump would give me enough juice? I'm going to jumper the wires/relay...and be sure the pump is working... I'm sure it is.. 94 jimmy 4.3 vortec 140k I gotta pick up my wife from work later and don't want to get stuck again...

Fuel pump relay is not powering the fuel pump. I was able at one point to jump the orange wire to the gray wire but it will not even do that now. I know the fuel pump works because I can jump from the battery to the gray wire and it will turn on.
I used a multimeter and tested the volts from the orange wire on the relay to the neg post on the battery and it is only reading about 1.3 volts. Is this normal?
Checked the fuel pump 15a fuse and it is ok. I am getting spark. Could it be the crank sensor? How can I test that? (It is above the start I believe). Could it be the ignition control module? How to test? Location? What else can I test with the multimeter and post back with the results to further diagnose?

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??

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...

Ok I have 94 B2300 and about every 3rd or 4th start the ECU relay will not come on / energize which the the fuel pump relay doesn't come on either to prime the fuel system... so no start! It's very intermittent and sometimes the only way I can get the truck started is by pulling out the ECU relay and plugging it back in even sometimes that doesn't work too. Is it a bad relay or bad base the relay plugs into or is the ECU/computer going bad or is there wiring messed up in my ignition switch? Is there a known problem like this with these trucks?

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.

I have a 1994 Ford 460 motorhome with a intank fuel pump that quits when it gets hot. so I was thing of butting a heavy duty in line pump on and just pull it through the old pump can this be done safely. Or is it best to drop the tank and just put a new fuel pump in.

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 ?

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?

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??

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.

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??

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?

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???

1999 4.6L won't start after sitting a month. Ran fine before, now won't start. Cranks fine. Cannot hear fuel pump turn on when key is turned. Fuel pump fuse is good.
Fuel pump relay clicks a few times when key is turned. Is this normal? I am hoping it is the relay and not the pump. What should I check next? The wires at the pump? What should they read?

I am looking for the location of the fuel pump relay for my 1999 Ford F550 V10 4WD Gas truck.
I have replaced the fuel filter and fuel pump. When the key is turned the pump gets juice and 2 seconds later is not getting juice. No lines are coming into it, so it's not getting up to pressure and shutting off.

I am trying to diagnose my fuel system, but I cant seem to find the fuel pump relay. My truck is an 2004 f250 crew cab work truck with 5.4L. it seems that the relay can be mounted anywhere from behind the radio or in the engine compartment as well as built in to the fuse box under the steering wheel.

2003 f350 5.4... Is the fuel pump relay behind the radio? Under hood? Or built in the fuse panel and unserviceable?
