Ford Super Duty (1999-2016) :: F550 V10 - Fuel Pump Relay Location
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.
Ford Super Duty (1999-2016) :: 2002 F450 Struggles Like It Is Low On Fuel
I have an 02 F450 with a dump bed an just under 45,000 miles (was barley used by the first owner). This maybe unrelated to my problem but is worth mentioning. This past week I noticed a small puddle where I had previously parked at a customers house so I checked the oil. I was about 2 quarts low. I followed the oil trail up and found a pool in the valley. One of the high pressure lines were loose and the seal was chewed up so I replaced it and tightened it. No more oil leak.
Now my new problem. Two days later, after about 45 minutes on the interstate driving about 75 mph the truck started to rapidly lose power as if it was running out of fuel. I heard a loud ticking sound coming from the engine and the more I tried to accelerate the worse it got. I pulled over and the truck stalled. I thought that maybe my fuel gauge had crapped the bed on me because it still read a little over 1/4 tank. I called a buddy and got more deisal in it and it started right up. We'll after about 5 minutes of 60 mph it started to happen again. So to fast forward... I opened up the tank and found the the strainer had crumbled in the bottom of the tank.
So I cleaned out the screens in the sending unit and replaced the strainer, replaced the fuel filter, and reverse blew out the lines. I read about checking the hpop reservoir for oil and it is present. So to sum up, as long as I stay under 60mph or so I can get about 5 minutes of run time before the truck starts to stutter and stumble. If I shut it off for about 5minutes I can go back up to 60 again but it the cycle continues. 5 on and 5 off. If I start the truck after say 30 seconds after shutting it off it sounds like it's going to die and has no power at all. I have worked on a lot of vehicles but none with anything like this and this is my first deisal. What do I do to get this beast back to normal?

I have searched through the site but have not found anything like the problem I'm having. I have a 2003 F250 5.4. Three weeks ago I attempted to start my truck and it just cranks. The fuel pump was not coming on. I left the truck over night and the next morning the truck starts with no issues. It ran normally for the next three weeks then the same thing happened again. Towed to the mechanic but the truck started up and ran. It shows no codes after both no starts and both times ran fine the next day. When running fuel pressure is where it should be.

I just replaced my fuel pump to avoid another tow truck ride and now my fuel gauge is off. I filled up the truck today and the fuel gauge is only showing half a tank. I turned the truck on and off several times to try to reset it, but that didn't work.
Truck is a 2003 with the 5.4.
Ford Super Duty (1999-2016) :: F250 - No Power To Fuel Pump Relay
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???

Carb rebuild and tune-up on my 370 and took for a test run. All of a sudden oil pressure was lost. I know catastrophic happened but was conned into dropping oil pan and put in high volume oil pump. now at 2000 rpm I have enough oil pressure to keep rods and mains from rattling but lifters are collapsed. At idle oil pressure drops to zero. It is a mechanical oil gauge. I know the tune-up had nothing to do with it but I did drive the truck about an hour before. A machine shop said the only way he knows oil pressure can be lost like this is for a cam bearing to come out [catastrophic].

View 2 RepliesFord Super Duty (1999-2016) :: 2003 F550 - Hubs Won't Stay Locked
Just got done with a ball joint replacement on my 2003 F550, everything went together great, just as it should. Until I got to the drivers side hub lock.
I have Mile Marker 449s/s manual hubs. Turn from free to lock and theres this loud clicking sound about halfway to LOCK (passenger side doesn't do this). Hub will stay locked for about 2 rotations, then it unlocks and makes a clicking sound. You cannot turn the hub back to FREE, it gets halfway and stops. I tried forcing it and broke the spring fingers inside. Have a new set on order.
Is this a locking hub issue or an assembly error? I was going to take these steps.
- Take passenger side hub lock off and see if it operates normally or same on drivers side.
- If same, remove axle and re-seat/re-assemble everything again
Anything to specifically check? All the parts went back in, washers were in correct order, outer snap ring is in groove.
Ford Super Duty (1999-2016) :: 2008 F350 - Loss Of Turbo Suddenly At High PSI
Bought a 08 F350 with the 6.4 Liter, with 80k mikes on it. Was traveling up an incline. Both Turbo's were engaged, when suddenly I lost boost, and PSI dropped all the way down. They barely create any pressure now. Checked intake, also checked boots too inter cooler. All seem fine. After driving it for about five minutes at low PSI, a check engine light came on. It was a sudden loss of power.

2003 F350 6.0L ... 171,000 miles ... 5,100 since oil change 15W-30 at the shop ...
I was driving on the interstate (50 miles of driving) struggling to maintain 70-75 mph at 2,200RPMs. I would accelerate and RPMs would go up to 3,000 but no speed. Before I could pull off speed slowed to 50 before dying. Sat on the side of the road 30 minutes before I could get it started. Had to give it gas. No misfires just quietly started. Couldn't go over 30 mph. Towed it to my destination 135 miles.
Volts on 7Pin FICM read fine.
Checked the fuel fulters. Air Filter. Tank for debris. Nothing.
My coolant reservoir was lose and I noticed a lot of coolant in the driverside front wheel well and down the left side of the undertruck. Reattached after checking FICM. Hope that was all it was cause I couldn't find any leaks.
I had Planned to have the oil changed before the return trip before this all happened. New to Diesel engines but I like a challenge. Where do I go next?
Ford Super Duty (1999-2016) :: 2003 - Loss Of Power / Gray Smoke
I have an early 03 f350 with a 7.3 liter 298,000 miles on it
Replaced fuel filter
New oil change and filter replacement, New icp sensor .
Deleted the baffle and installed a cone air filter with the air sensor installed in the neck .
I Was driving home one day and the truck just slumped into this huge power loss . Couldn't get over 2200 rpms and barely made it over 30-40 mph.
Truck in park - idles like crap and still won't go over 2200 rpms when holding the pedal to the floor . And it has what sounds like a miss at a struggling "full throttle" (22-2500) rpms - thought it could be my icp sensor - replaced it -- no change
Checked driver side wiring harness -- no damage chafing found -- did a fuel can to pump test no difference - and today after I reinstalled the fuel line right after I ran my can to pump test I let the system prime . Started the truck and it ran for about 40 seconds and died and wound not fire back up and would just miss and spit and sputter -- lots of gray smoke though- but it fired up a few hours later after I let the batteries sit on charger .
Now before all this happened - I noticed the truck had a bit of a gutlessness to it as I would be piddling around around town and it would have this hesitation in power kind of like a slight jerking feeling , now this truck was so gutless since the day I got it ,I couldn't even burn out on a gravel road without the throttle going limp and the check engine.
Light kicking in so I figured I'd give it a bit of hotshots secret and see if It would maybe flush the injectors but it really made no difference...
Ford Super Duty (1999-2016) :: 2012 F550 - Horn Not Working / No Power
I am trying to figure out where the relay would be when i look online for the map of the relay box under the hood it says nothing of a horn relay. I don't have a key fob for the doors to unlock so I wouldn't think its tied to the computer. Should mention nothing happens when you hit the horn also fuse is fine. No power at the actual horn when i hit the steering wheel(horn)....
View 8 RepliesFord Super Duty (1999-2016) :: 2000 F550 Lost Power / Shakes And Dies
I have a 'new-to-me' Ford F-550 with the vaunted 7.3 Powerstroke diesel engine. The truck only has 120k miles and ran great when I bought it. Last week it began acting up. While driving on the highway, it lost power, began running rough, and once I pulled over, it died.
After a few minutes, I tried re-starting the truck, it started, but had little to no power....I could get up to 30-35mph and then it would slow down and lost all power. I let the truck sit for about 20 minutes while I refilled the diesel tank, it started right up and drove normally for another 10-15 minutes and then the same thing happened again.
The truck sat for a day and then drove normally for two entire days. This morning, it began acting up. It is the same as before..... what to do with this type of issue?
There is not a check engine light lit (yes, it works). The diesel is from a good source that is not causing problems in anything else. The truck is otherwise strong.
Ford Super Duty (1999-2016) :: 2003 F550 - Batteries Not Charging / Instrument Cluster Does Not Work
I have a 2003 F550 6L diesel flatbed truck. Last week, the overdrive button would activate by itself. I'm assuming there was a loose wire so I taped the button to keep the overdrive off. Two days later, the overdrive came on while the button was pressed in and then smoke came out of the steering column/lever area. I pulled over and turned off the truck. The smoke stopped after 10 seconds and I restarted the truck. The overdrive light/functionality no longer worked and the instrument cluster also wasn't working.
The next day I was driving, and the truck died at a stoplight. I got it towed home, and opened the steering column and noticed that the overdrive button wire had burned. I removed the harness clip and charged the batteries. It started but the instrument cluster still didn't work. 2 minutes later the truck died. I replaced the alternator but still it won't charge the batteries. The truck dies 2 minutes after getting a battery boost to start the truck. The instrument cluster also doesn't work. What could be causing this issue?
