Ford Wiring/Electrical :: Fuel Pump Keeps Blowing A Fuse
May 10, 2016
I have a 1994 Ford Ranger king cab 4x4 with a three inch lift kit on it . My problem is the fuse is blowing that goes to the fuel pump . It started out blowing the fuse now and then when it was raining . Well I thought it mite be the fuel pump going bad but after I put the new pump in the truck it lasted about a week and started blowing fuses again . I put another fuse in and it go a few days and blow it . Last week on a 100 mile tripe I got almost there and it burned a fuse on the highway . I tried to put another fuse in and it would blow it as soon as I tried to start the truck . Burned five fuses right then . So I had it towed to mothers house and put another fuse in and it cranked up . I looked at the wiring that was not wrapped in that plastic cover stuff and have not found anything yet ...

2006 F-250 SD... I Keep popping the 15A #17 fuse under certain conditions - Driving forward
1. Start with good fuse.
2. Start engine, while in park, turn on parking light...4.8A on circuit. No problems.
3. Put into reverse and drive. down the block around the corner and back up to the house... No problem. 4.8A on circuit.
Put the shifter into drive and - POP - the fuse goes. I never see a jump in the current. 1-5 seconds until fuse goes. While conducting testing, I have had the fuse blow when shifting from reverse to park. Looking at the wiring diagrams, I don't see a common wire that would cause a short when shifting. What I should try next?

My 2005 4.6L 4x4 screw is blowing the 10amp a/c clutch, 4x4 solenoid fuse whenever i turn the a/c on, at times whenever I turn the defrost on. the fuse does not blow when i turn the key to power (no engine start) but when engine is running fuse will trip. I disconnected elect. Connection at compressor and fuse still blows, also seems like no power or life from compressor.

I purchased a 94 Ford Explorer 4x4 4.0L w/ Automatic transmission with Overdrive. Great work truck, but I am finding that these had a lot of wiring problems. First thing that messed up with me is the backup lights wouldn't work. Then the dash lights and parking lights stopped working (Still no fuses where bad). Then about 2 weeks later, I was on my way home when It just died like someone had turned the switch off, I pulled off the side of the Interstate, and after checking my fuses/Relays under the hood.
I found that the EEC Fuse (30AMP-BIG Fuse) had blowed, I didn't have one and the truck wasn't off the road good, So I wrapped a small wire around the fuse to see if I could start it and get it out of the road better, It started right up, but soon as I pulled it off the road it died again, and I found that it melted the EEC Relay, I went to the parts store and got a new relay and fuse and put them in, It blows the fuse as soon as I put it in, with the switch off or on. I just need to know what things will cause this so I can check them out one by one, until I find the one that is causing this problem, cause It run great up till this happen.
Only other thing I may need to let you know, Is when I bought it, the key switch would start it, The guy had put a push button starter switch that you push to start it with the key on, I unhooked it, and it started fine with the key for a while then it stopped again, so I had to hook the push button back up and had been using it until it stop running with me.

I posted earlier about the tranny in my 01 Ex v10 having a transmission problem. The show looked at it and found the O2 sensor had shorted out and in some way sending the truck in to limp home causing the tranny fuse to blow????
Any way they fixed it or so they said and I drove it for a few hours and it did fine. The next morning I drove it and it blew the fuse. (under hood box I belive #19) I took it back to the shop and they beat and banged on it....got it wet etc. and can not get it to do it again. I know whe have an electrical issue but what all runs off of the fuse that controlls the tranny?
Is there any online wiring diagrams of excursions or superduty drive trains? Where all to look for the problem?

2001 F-350 diesel. Out of nowhere, I start the truck and there's no turn signals. Fuse is blown so I replace it. It immediately blows. Tail lights work. No turn signal, brake lights, or hazards. I haven't hooked up a trailer or done anything abnormal recently. Only the #1 fuse (20Amp) is blown. Pulled bulbs and they work fine. Inspected wiring under and near lights. NOTHING! Any way to localize a short?

I have a main tank and an Aux tank with a gauge selector switch. I believe I may have a bad fuse as the indicator has stopped working. Where it is on the fuse block??

I'm having brake light issues with a 2001 Suzuki Grand Vitara. The brake light fuse keeps blowing. The last time driven with me following the driver side brake light was dimmer than the passenger side. At one stop the driver side brake light pulsed brighter for a split second then went back to dim. A few stops later it became as bright as the passenger side and stayed that way for the rest of the trip. The driver put in a breaker fuse and it was in during the observed trip. I'm not sure of the brake light visual symptoms without the breaker fuse in other than that the fuse keeps blowing which prevents the vehicle from being shifted out of park. What the problem could be? Bad ground?

I have a 2000 F150 with @175K miles. Replaced the clutch about a year ago, replaced the front calipers a few weeks ago, due to the right front locking up on my way home from work. Since then, when I try to start, it blows the fuel pump fuse. (#10)...

I have a fuel pump I want to install I want to hook this thing up on a switch inside the cabin to be used as kind of a security device, but I am hoping I can wire it into the ignition as well.... I want the pump to activate when the ignition is turned on but only if the (hidden from view) switch is in the "on" position. Not sure if all this is possible.
I have heard I ought to utilize a relay to avoid voltage loss at the pump. I have never hooked up a relay to anything before although I have heard of them being used. This system is being installed on a 1967 F250.

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?

My R32's Fuel Pump Fuse keeps blowing. This started after driving my car in a bad rainstorm. I think water may have gotten in the door which could be causing the short, but I am not sure. This car has two fuel pumps as it's been modified. I know for a fact the main fuel pump works as it did prime after replacing the fuse (then letting the car sit over night then opening the door). Right after the fuel pump primed though, the fuse blew. I decided to replace the fuse and start the car. The car started and ran for maybe a second or two before the fuse blew. I took a look at this thread in regards to the fuel pump not working as I thought the fuel pump was dead till today. I was wondering what are the possible problems that could be causing the fuse to blow? Could it be the relay? Could it be the switch in the door shorting? Also, where would I find the relay? I know it's under the dash, but is it under the panel on the passenger side or driver side?

The fuel pump fuse keeps blowing intermittently. I would assume it's a wire grounding out somewhere but I can't seem to find one yet. I do have a faulty purge solenoid on the canister but I don't think that would cause this. The reset switch doesn't seem to be tripped either.

Ok so I just bought this car, 1993 pontiac grand am se, from a neighbor. When I test drove it, the back seat was all unscrewed so I thought no biggie and it drove really nice for being a 1993. Ended up buying the car. I get the car home, husband puts seats back together and we go to leave for town and the fuel pump fuse blew. Put a new one in, go to start the car, fuse blows again! Tow the car home. Husband checks the wires to make sure there is no faulty wires. Has to reground the ground wire. Car then starts. Go to drive down my driveway and the dang fuse blew again! Mind you there is a new fuel pump in the car so we know this isn't what is wrong with it.

When I changed the alternator on my 2000 plymouth neon, I crossed the wires for the plug. Now the fuel pump fuse keeps blowing, when it turns over, which isn't often. I turn the key and nothing happens.

OK, this one has me stumped...I have a 93 F150, 302 with the E4OD. I know the transmission needs to be rebuilt (probably a bad pump). When I put it in reverse, the engine will start to bog down and will die unless I put it back into park or neutral.
If the engine does die, the fuel pump does not prime with the key "on" and the engine obviously will not start. If I let the truck sit for about an hour, the fuel pump primes like it should and the engine starts right up. The fuel pump shut-off does not trip and all fuses are good.
