Ford Wiring/Electrical :: F350 Truck Would Act Like It Ran Out Of Gas Then Pick Up And Go Again
Oct 1, 2014
Truck is up in the back country and has quit. It has two factory gas tanks, I can't hear either of the fuel pumps will come on when you turn the switch on. The problem started as an intermittent fuel starvation issue. Truck would act like it ran out of gas then pick up and go again. Switched tanks back and forth but it got worse throughout the day and finally will not start at all. I have listened to both tanks when the ignition switch is turned on but can not hear the pump come on for either tank (switching the selected tank with the switch on the dash). We went through some bumpy terrain just before the problem started so I am thinking maybe a wire might have come loose or got broke somehow. I am asking for wiring schematic so I can check for voltage in the correct place going to the fuel pumps. Both tanks are full of gas so for now dropping either tank is not an option.

I just bought a used F-350 that was being used by a fire department. They did something to the wiring to where most of the electronics won't work unless the key is in the "ON" position. When I open the doors, the dome light doesn't come on, nor does it come on with the IC dimmer switch, when I turn the key either backwards or to the "ACC" position the radio won't work, the headlights DO work but I don't get the warning chime when I open the door with them on.
The flash-to-pass works, as do the hazards and the turn signals (which seems odd -- I don't recall having a car where the turn signals worked without the car being on). With they key on, everything works including the dome light and the door chime. Is there some simple thing they could have done that would make it work this way and is easily reversed?

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?

Having a chance to try an O2 Sensor Simulator on your truck? I am wondering if they actualy work or if I should just stay away from them. Are there any problems or improvements using a SIM?

I have a 94 Fsuperduty with a flatbed and lift that folds up and stores under the end of the bed. Recently while on a job the lift wouldn't go up, so I checked the one fuse I know of in the system and it was burnt. Put a new one in and before the lift reached the top it burnt-out again. It had been working with no problems for months prior to then.

I have a 2006 F350 Diesel. Had one of my employees go out to start the truck yesterday and when I went out I had no electrical power to most of the accessories (gauges, warning lights, power windows, radio, interior lights, turbo charger). It also seems to have no power - could barely make it go up the slight incline into my garage. I have checked all the fuses - they seem fine. Although put a tester on the interior fuse box and I don't have any power to the fuses that run these accessories.

I have a 1999 f350 crew cab. There is a gray box with some wiring running to it and when the door is open I here a little cracking and popping sounds. It is between the steering wheel Column and the ashtray under the dash. I can hold it and feel it clicking and popping, What that is called, or how to get it out to replace it?

My truck has been sitting more lately, which means up to a week without starting and running. Each time this happens I run into a dead battery. And I mean dead. I've charged it full and then used the truck no problem.
We did a test where we unhooked the negative terminal wiring clamp and ran a meter to check for amp draw. We did this by touching the meter leads to the negative post clamp (unhooked) and to the negative post on the battery. It gives a reading of ~1.5 amps. Trying to figure out where the drain might be.
We'll jut pull each fuse to see if we find the electrical area drawing the amps.

I am beginning to think that I need a whole forum dedicated to my trucks wiring issues ... I finally got my reverse lights to work but my newest issue Is that while driving tonight i lost power to my parking lights, my instrument cluster lights, and my heat control lights... everything still works inside (gauges all act properly but they won't light up) and i still have turn signals and brake lights, and headlights. I really don't know where to start with this one. I don't have an owners manual so i can't figure out what fuses to check or what relays to look at. It is a 2007 f350 diesel....

My 2001 F350 Super Duty diesel keeps draining my batteries for some reason, wouldn't crank on Friday. Put my battery charger on for a few hours and it started fine. The rest of the day fired up fine, on Saturday it happened again. Had both batteries charged and load tested today, they are good. Short???

Repaired my locks on my F350. Had the motor reversed. Before I figured that out I thought I needed to change the wires in the plug. Changed them and it didn't work, put them back and now the switch on that door does not work for the lock; however, all other switches work. What do I need to fix?

I bought a great 76' SuperCab with a 390 4 barrel Wednesday (the 30th) and while driving around the neighborhood this evening the truck just lost all power and came to a stop. No lights, no engine, nothing and I cruised to an easy stop (fortunately at the end of my own block). I thought I smelled a bit of electrical burn for a moment after I came to a stop but could not track it down before the smell disappeared.
Some early symptoms - on drive home from purchase, the turn signal light function was in and out. The starter was also turning slowly and sounded tired/weak. The ignition switch was a bit loose and previous owner said you had to make sure the key was not all the way to the right or accessories would not work.
Some early checks/fixes- replaced battery and battery cables and checked grounds. Starter began turning stronger and turn signal lights were back. Thought I had it going well.

My 85 f150 5L is parked to far in into my alley.. the last time i saw my keys i moved it up to water the plants that it was tucked almost on top of.
ive been looking for the keys for 2 months.. the truck isnt being driven at all but i think my neighbors are getting mad at it being out so far.
I can get in the engine bay, and i have jumped the starter on our big trucks at work before.. but what wires do i have to join to put the ignition into the run position?

Long story short, my truck's front turn signals and rear turn signals/tail lights won't work. I am thinking that the relay is burnt. Whenever I look in the manual I can't seem to find the location for this relay. Is is built into the flasher?
Also, I am just assuming because the rear turn signals and tail lights are the same bulb that fixing this should clear up both problems. Am I right in thinking that?
I have already checked all of the fuses. Also, the Hazards don't work either.

I have a 1990 F-350 7.3 lariat crew cab. The tail lights fail to work but all the turn signal and brake lights work. I changed the light switch located to the left of the steering wheel but that didn't solve the problem. all the fuses under the dash appear to be ok to. Is there another fuse for just the tail lights.

I am having issues with my auxiliary relay on my truck. It will work intermittently. It started with me just needing to give the relay a light tap for it to work, and is now progressed to needing me to push really hard on the relay for it to turn on, but then as soon as I let go it shuts off again. I have replaced the relay with a new one and it's doing the same thing, and have even tried some di-electric silicone on the terminals with no success.
I was thinking of pulling out the entire fuse/relay panel and see if the contacts have pushed out, but then I read a thread regarding the panels and issues involving the removal the terminals and breaking the panel. 2004 F350 CCSB 6.0L...

Over the weekend I was driving my 2000 F350 and the alternator died (found out later). The shop said they replaced the alternator but it wasn't charging. They later told me it was because the isolator failed. My 2nd battery WAS a yellow gel battery. Before the battery (in series) was an 50 amp circuit breaker...........that blew apart.........and the battery had a melted off side terminal. It looked like the 'sealed gel battery" had been 'leaking for a while" (as there was funky acid type white corrosion deposits in a few places. Any speculation what happened here?
