Ford 7.3L Power Stroke (1999-2003) :: Ran Out Of Fuel With 1/8 Tank And No Low Fuel Light?
So my 7.3 started sputtering and lost power, died on the side of the road. I wasn't far from home put about 8 gallon of diesel in the tank with a couple of fuel jugs and it fired right up.
Gauge was reading 1/8 of a tank and low fuel light did not come on. (low fuel light comes on when you start) Gauge came up to about 1/2 after putting fuel in.
What happened? Gauge was always reliable and low fuel light always did work. Only work done to fuel system was had new tank straps put on a couple of months ago.
Ford 7.3L Power Stroke (1999-2003) :: Fuel Tank Plastic Ring Nut Start?
Having trouble getting large plastic nut to start threading on top of the fuel tank sending unit, after doing in tank mods.
It just doesnt seem to want to start threading on properly. Its always cocked when it grabs, and after a while opposite side pops up and it falls off. Not sure how to get it back on there
Dealer has new ring for 18 bucks, maybe mine is warped or dried up since 2000?
Ford 7.3L Power Stroke (1999-2003) :: Crank But No Start With 1/4 Tank - Bad Fuel Gauge
1/4 tank just kept cranking. Added some diesel and started right up thought it was bad fuel gauge. Went about a mile and shut down just off. coasted went got more diesel but this time cranked but no start. anti theft light was flashing too.
Towed home started right up after tow... Starting now... Tomorrow was going to change the fuel filter....
Ford 7.3L Power Stroke (1999-2003) :: Erratic Fuel Gauge - Level Would Register Full When Only Half A Tank Or So
I've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.
After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.
You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.
I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

I recently purchased a 2003 F250 Super Duty with a 6.0L Powerstroke Diesel. The truck came with an auxiliary fuel tank in the bed, but how it works. There is a keyed switch in the cab next to another regular switch, and I have not had the courage to try either of them yet since the whole thing looks like a DIY job. I did look under the truck, and can see what appears to be some sort of solenoid setup.
Just wondering, how it works and if it is safe to operate. I do not see any rollover valve, and want to make sure I do not overfill the tank if I use it.

01 7.3. Cranks, won't start. Tank was at 1/4 but is full now. The lift pump runs, I can feel and hear that the motor is spinning when I cycle the key. I removed the fuel filter and cycled the key and get no fuel into the bowl. It looks like the lines are stainless from the pump to the tank so I doubt it is sucking air. I pressurized the tank with a shop vac and I get fuel coming into the filter housing. Am I missing something obvious? I have never seen an electric pump that would run and not pump fuel. I removed the suction line at the pump and don't feel any suction there.

When I fuel up and open the cap on the filler neck I always hear a hiss. Never could figure if it was pressure or vacuum. Today, after changing oil, I opened my fuel filter bleeder to check for water and it just started slurping and gurgling with no diesel coming out. I lowered the truck, removed the fuel tank filler cap and heard the hiss. Raised back up and opened the filter bleeder and diesel came out. I now know the hiss is a vacuum. Is this normal? If this tank is vented I have a problem somewhere.

2003 F-350 - 7.3. With the key in the on position there is zero voltage to the fuel pump. Fuel pump fuse is good. I traced the red with black tracer wire from the pump up through the firewall and to the safety inertia switch. The switch has continuity so it's OK. Then from the safety switch I traced the green with yellow tracer wire to a fuse block plug connector. Then I checked continuity from that connector out to the #40 fuel pump fuse and it's open.
So I then i checked from the fuel pump fuse to all the back connections on the back of the fuse block and there was no continuity to any of them. So I removed the back cover off the fuse block to expose any issues. I found two board mounted relays. Now, from the fuse I get continuity to one of the relay connections. So did Ford hide the fuel pump relay and make it non replaceable? Also if this is the pump relay then what circuit energizes it? I need to make sure before I replace the fuse block.

View 13 RepliesFord 7.3L Power Stroke (1999-2003) :: Low Power - Fuel Pressure?
Low power on my 2003 7.3 F350. The truck runs fine but I can tell it is low on power (seat of the pants). I figured it to be fuel related so changed fuel filter and oil with no change. When that didn't work I installed a fuel guage and this what I found. Key on no start fuel pressure 45 psi. Start truck the pressure will get up to 61psi. Under a load it will drop down to the low 30s. I have dropped the tank mixing chamber screens clean and so was the tank. Changed fuel pump and now under a load it drops to the high 30s. Does this sound like the fuel pressure regulator is leaking by and causing low pressure under a load? Truck is stock besides superchips 1705 programer.

View 9 RepliesFord 6.7L Power Stroke Diesel :: Slight Leak From Titan Fuel Tank
I've had the Titan fuel tank installed for about a month now and am loving the extra range, although this morning I walked by the truck and got a slight whiff of diesel by the fuel filler door. I pulled out the flashlight to take a look, and noticed a really small, faint trail of diesel fuel running down the driver's side of the tank near the rear strap.
I crawled under the truck to inspect it as best as I could in the driveway, feeling around the sender, filler, and vent tube connections, and didn't notice any obvious puddles of diesel. About the most I got was some dampness around the sender unit seal, but it wasn't much, and could even be residue from the fuel lines dripping during installation of the tank. Based on where the trail down the side of the tank has formed, my best guess is it's going to be a filler or vent tube hose clamp that I didn't get tight enough.
Unfortunately I just filled the tank up last night and am headed out camping for the weekend this morning. I followed all the install instructions exactly, making sure to check the torque on the sender unit seal four times before installing the tank back in the truck because I didn't want to deal with any leaks, so I really hope it's not that seal. I also filled the tank up to the brim right after install and crawled all around it a day or so later and noticed no dampness or leaks. Needless to say, I'm not looking forward to dropping the tank again and then potentially waiting on parts if something is defective. I'm waiting on a call back from Titan to get their advice.
Below are a couple pics of the weepage. Obviously not a huge leak, but something I want to get taken care of ASAP.
Ford 6.7L Power Stroke Diesel :: Whining Sound By Fuel / Def Tank On Startup
The truck now makes a whining sound for about 30-40 seconds on a cold startup from the fuel tank and def tank area . what could this be ? Its at the dealer for other issues also , the dealer said that it was my starter making the noise, I'm pretty sure the starter is attached to the motor and not located by the fuel tank....
View 8 RepliesFord 6.0L Power Stroke Diesel :: 2005 F250 - Fuel Gauge At E With 1/2 Tank?
2005 F250 Superduty Crewcab 4x4 6.0L diesel/auto
Wife drove the truck before me and bunched the floor mat under the pedals. I didn't notice the mat issue when I drove the truck today. I accelerated fully after doing a left turn onto a busy highway. The motor spun up hard with the accelerator floored but because of the mats, the pedal stuck all the way down. I was approaching stopped traffic while under full acceleration and I shut the engine off and pulled over to the shoulder all while braking hard ( it was a hell of a ride!). I freed the pedal and restarted the engine.
Now, despite a bit less than 1/2 tank of fuel (I have the 38 gal tank), the dash readout was showing "Low Fuel", the gas gauge was below E and the engine was running like it was running out of fuel. I turned the engine off again and left it off for 1/2 hour before restarting it but the gauge and engine still behaved the same. As I drove to the nearest diesel station, the engine was not running "right". Of course the station I pulled into had 1 diesel pump and the pump was broken.
Because I thought I might actually be out of fuel, an understanding stranger took me to the store to buy some gas cans and then to another station to get 6 gallons of fuel. I got back to the truck and added the 6 gallons of fuel. When I turned the key on, the fuel gauge immediately came up to 1/2 tank. I then drove to that other station and added another 15 gallons of fuel to fill it. This confirmed that I had about 18 gallons of fuel in truck when the "Low fuel" warning occurred.
So, what the heck was going on with the fuel gauge? I am sure the "Low Fuel" warning is tied directly to the gauge but why was the gauge reading low? Is it possible that the "Key-off" while under full acceleration followed by hard braking had confused the ECU? I am just trying to figure out if I have a fuel sender problem or a confused computer that corrected itself. Until this incident, the fuel gauge has never been a problem but the wife messing up the mats has been an issue!
Ford 7.3L Power Stroke (1999-2003) :: 1999 - Cranks But Won't Start - Water In Fuel Light On?
My 99 F350 cranks, but won't start, and the "water in fuel" light on the dash stays on while cranking. I have never paid close attention to it in the past. Is it supposed to be on while cranking?
I drained the water from the yellow lever located on top of the engine, and tried to start it. The light went off for the first few cranks, but again the truck still will not start.
I just came from a 10 hours round trip to NC. I filled the truck up two times from gas stations on the way. Is it possible that the fuel is bad? I drove on the same fuel almost 3/4 of this tank and now at the last 1/4 I am having this issue.
A little update:
I took the top of the fuel bowl off to see what the filter looks like, and it is nasty and completely black. I could not tell if the fuel in the bowl contained any water, but it looks greenish and uniform, no the obvious separation that happens when you mix water and oil.
Could the fuel filter be the problem?
A little history about the truck. It's always hard to start if cold and not plugged in overnight. I know it's the glow plugs relay, so I just keep it plugged in all the time until I get a chance to fix it.
IDM was acting up shutting off half of my engine, but I took it off, cleaned it, plugged it back in and it has been working fine for over 2 months.
