Replaced glow plugs 2 weeks ago, did great until the relay went out, expected that. Now the thirty amp fuse for the relay blows when key is turned on. Where to start with electrical problems.
View 1 Replies2004 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??
I want to install a set of upfitter switches but my truck didn't come with them...so I bought the switches and the relay/wire harness as well...I cannot find any good information on where to mount the relay and where an extra plug on that harness goes too. I have found the wires that attach and go through the firewall but I am not sure where the rest of this mess goes...my truck did not come with the wire harness already installed...

View 1 RepliesMy neighbors 02 250 6.8l the turn signal/hazard relay is clicking with key off, sounds exactly like a turn signal when truck is off and switches are not engaged. Here's the weird thing, if you hit the brakes the relay stops clicking, if you engage the turn signal or the hazards the lights on the dash are in time with the relay as it should be, but when the turn signal switch or hazards are turned off the relay keeps clicking except when you hit the brakes. Also the turn signal will work with ignition off, if you pull the relay out the turn signals and hazards are inoperable but the brake lights still work. I swapped in a new relay and same thing...
View 8 RepliesMy 2004 F350 would not start yesterday, for the second time. I had just been driving it 30 minutes before, but when I tried to start it nothing happened. The dash light came on but nothing else, not even a click. Had to leave it overnight, and this morning it started completely normally. what this might be? It seems kind of like a relay or reset that was cut off and took time to reset itself. The first time it happened, it started up after 20 minutes, but yesterday it still wouldn't after an hour at which point I had to go to work so I don't know what the interval would have been if I could have stuck around and continued trying it.
View 6 Replies1999 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???

View 6 RepliesI 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 was getting ready to run a fused wire from the battery to the rear of the truck to power my bed lights. Then I read where some owners have jumped the trailer charge relay socket to provide constant 12v at the 7-pin trailer plug.
I never keep my trailer cord connected to the truck when camping so the chances of the trailer draining the battery are nil.I don't want powering the bed lights from other sources as I have decided I want 12v to bed light switch always available.
I have a new f350 with 1500 miles and the check engine light came on. Took it to dealer he said it was the DEF heater. He replaced that part and then it came back on and now its the GLOW PLUG RELAY MODULE. Now for the good part. Ford told dealer that I could drive the truck with the CEL on. Ford stated that they were remanufacturing the glow plug relay and that is was not available at this time and not sure when it will be ready. I filed a complaint with ford, but with little success. Not sure what else to do about this issue.
View 2 RepliesI have an 02 F250 6.8 with 51,000 miles on it. I recently replaced the battery about a week ago, and only actually drove it yesterday for the first time since replacing the battery. I drove it about 25 miles, parked, and when I went to restart, it wouldn't. The starter doesn't crank, so I mean its not a cranking issue as in cranking, and not starting. It only clicks at the relay when turning the key. It acts like when you try to use a wrong chip coded key.
All of the dash lights came on, and I can hear the relay clicking, but that's it. I swapped the relays around, and no luck. If I let it sit a while, about an hour, it will fire right up. The battery cables are tight and free of corrosion. I am curious, since I just put in a new battery, could this be the culprit? Why will it start fine cold, but not hot? I have NEVER had an issue with this truck until now.
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.
View 14 RepliesI have a 01 Ford excursion 7.3 auto and it will not start unless you jump the starter relay, I have replaced the starter, starter relay and swapped out batteries from my 2000 F250 auto, not sure what to do and this is my daily driver. Not sure if this matters but just had the transmission rebuilt. I have tried searching other threads but still not finding what I need. Once it starts it runs and drives. When you turn the key you hear a click like a relay is engaging and all of the lights and gauges work it just won't start with the key.

View 5 Replies2003 f350 5.4... Is the fuel pump relay behind the radio? Under hood? Or built in the fuse panel and unserviceable?
View 14 RepliesI have a 2001 for f250 with the electronic shift on the fly and when I turn the switch to put it in 4hi or low nothing happens I don't hear a click and the lights don't come on but the 4wd light works it comes on when I first start the truck and I put different relays in that we're good and still nothing I tested the the relay box itself for power and there wasn't any.
I used the truck last year for plowing and it worked sometimes it wouldn't go In or come out but after a few tries it would end up working but I've tried everything I could think of I'm starting to think it's something electrical because the relay box isn't getting power to it but idk if a vacuum leak would do that or a bad transfer case motor or iwe solenoid or if it's something more like a broken wire some where.
The #8 fuse under the hood was blowing on my '00 F-250 every time I turned on the healights meaning I would lose power to my park lights. The brown wire coming from the back of the headlight switch showed a dead short to ground that I traced to somewhere between the switch and the firewall.
Anyway, I got tired of trying to pinpoint the ground fault, so I cut the brown wires at the back of the switch and under the hood at the top bolt-on electrical plug and replaced the bad section with a new wire. It works fine now with the only exception being I do not get the park light flash when I hit the remote lock button the second time. I do still get the horn chirp.
My Haynes manual indicates there should be a relay box with a Park Lamp relay, Driver Unlock relay, All Lock Relay, and All Unlock relay. The park light relay looks like it sends the blip of power to the park light circuit. Where this relay box is? I'd like to splice into the brown wir coming out of it to restore the light flash when I lock the truck since sometimes it's too noisy to hear the horn.

View 1 RepliesTruck was dead- 2001 F250 V10... Has a starter relay (solinoid) behind battery... put a new relay in there- no go- cleaner terminals... then I put key in start and shorted the 2 terminals in the relay and she cranked right up. That would mean the starter is still good correct?? something in the ignition system?
View 1 Replies2004 F250 SuperDuty 6.0L Diesel. The turn signal (left or right), it would make a buzzing noise, so I located the relay under the steering wheel (by putting my hand on it and seeing which one was buzzing) and replaced it, I bought a replacement at Schucks, then the buzzing noise went away, and the clicking noise is back.
But.... I don't see the turn signal lights in the dashboard and the turn lights are not working, I checked, what could be the problem ? I read the owners manual, in the fuse box under the steering wheel, fuze #18 is used for turn lights, but it is not blown.
