Ford Super Duty (1999-2016) :: 2003 F350 - Fuel Smell In The Cab?
Jan 29, 2014
I have a 2003 F 350 Diesel. When the heater is on, I can smell diesel fuel through the vent. This happens mainly when I am at a stop sign and the fan is on high. I did some research on this forum and found some others with a similar problem. The question I have is it seems like some said it was the cracked injector cups or a leak at the reservoir on top of the motor where the filter is. What I wasn't sure of was the symptoms. If it is a crack injector cup, would the smell be all the time and not just when I am stopped at a stop sign? Or would it be intermittent as well? It is definitely not exhaust smell. It smells like fuel. If it is the gaskets in the reservoir, I think I will do the blue spring replacement cause that seemed to improve a couple things based on the treads of the forum. I do see drips on the pavement every once in a while at the front of the truck towards the passenger side of the truck. Not all the way to the side near the tire, but off center on the passenger side. Is there anything that could be leaking fuel on that side of the motor?

New to me 2003 F250 Super Cab 6.8 V10. Great condition inside and out. 68,000 miles. Began smelling fuel (gas) a few days after driving it 250 miles from purchase location. Traced leak down to the top of the gas tank. Staining was visible around the rear vent. Applied about 5 psi to the tank and sprayed soap around until I saw bubbles coming from a hairline crack at the rear vent connection. Its where the fitting for the hose comes out of the tank.
My first choice would be to hot weld the crack. I'm not very comfortable with the idea of a heat source near a gas tank. I'm not sure, but the heat from the plastic welder might be hot enough to ignite fumes? Second option is to try some industrial 2 part epoxy (PIG) and seal it with that. Is there pressure inside the tank, and if so how much? Can try this fix with epoxy or JB Weld?

I have a question on the 2012 F-350 with 6.7. I have found after mid to long drives when I shut the truck down I can smell coolant when walking around the front of the engine. Seems more so from the driver side but i have yet to see any leaks or wet spots on the ground. I had the water pump and lower rad hose replaced last year under warranty and though it might have been residue but after a year and still smelling it it has to be something else. I only have 30,000km's left under warranty so if I need something replaced it should be soon

I have a 2002 ford f350 triton 5.4 V8. I just put front brake pads on my truck today. Started driving around and i could smell burning brakes. Stopped and alot of smoke was coming from my brakes on my front passenger side but nothing from the front drivers side. Replaced all the brake pads on the front. What is making them so hot?

OK, I have a 2002 F350 with 160k miles that cranks fine, but has a hard time starting when it is cold. By cold I mean that it is not hot from being driven in the last 5 hrs or so. No problem starting after being at rifle practice for 3 hrs or after a trip to the store. Always have trouble starting in the morning, like this morning when the temperature outside was 49 deg. I have to crank for quite a while to get it to turn over, but once it catches, it runs like a champ. Afraid I'm going to wear my starter or batteries out because It seems like I have to crank for about 2 minutes.
I have a fairly new CPS replaced less than 15k miles ago, new glow plugs, and recently replaced the leaky bleeder valve on the bowl. This difficult starting condition came about some time before the bleeder valve seal repair, and is still doing it after the repair. This problem seems to have cropped up on it's own unrelated to any work I have done. I am using Mobile 1 5W-40 diesel oil. When the no start occurs, there is no smoke present out of the tail pipe like what you would get if you had bad glow plugs. There is just no fuel getting into the injectors.

I bought my 2005 F-350 Diesel 6.0 Brand New. Whenever my low fuel light comes on, I only have a few miles to go before I run out of diesel. Is there a way to adjust this light so it will come on with maybe 20-30 miles to go before running out? Its seems to only have maybe a gallon in the tank when this light comes on...

I have a 99 F350 with a 29 gallon tank. I filled it up yesterday and the total gallons was a little over 24. The low fuel light was on and the gauge only goes up to almost 3/4. I recently bought this truck. I've searched for a thread on here possibly addressing this but have been unable to find one. I've been going through possible issues in my head.... What the problem is?

My 2000 F-350 during fill-ups will spill out about a quart or more of gas from under the truck somewhere right when the filler clicks off. Also can smell fuel sometimes when between half and full tank. 2000 f350 SWR crew-cab 4x4, 5.4 gas.

I have a 1999 f350 with the 5.4l engine. I have no power to the fuel pump or fuel pump relay. I have battery voltage to the pcm relay. I don't know what else to test because I don't have a proper wiring diagram.

So here's the deal, crank no start its getting fuel. Has base oil pressure and i put a ficm on that test good with a voltage meter key on engine off and cranking. I haven't hand any trouble finding info on this issue so. We can keep picking away. Just cant find anything about this.
A buddy of mine who has been trying to figure it out for me, Got it to start using a starting fluid. And it would run if someone was pushing the gas peddle but wouldn't idle. Or start without the starting fluid.

2 nights ago changed the fuel filters for the 3rd time on truck since bought it a year ago. It has 67,000 miles. F350 6.4 L 2008. The truck ran for about 2 minutes and then wouldn't start. For the last two nights have done everything including cycling the key over and over to purge air, replacing the fuel filters thinking the first ones may have been defective, pumped the gas pedal while trying to start it, tried to start it with fuel cut off switch held in, changed o rings etc. The first night I didn't get fuel at the head but after changing the filters a second time, I now have fuel at the head. That is the only progress I have made. The truck has gas and it is fine as we are using it in other trucks. The battery has never been allowed to totally deplete.

We just bought and '05 F350 Turbo Diesel, about two days after getting it the check engine light came on. We had the dealer check it since the mechanic wasn't in and it came up as "Fuel Level Sensor" . My husband can't remember the exact code. We have been told it's no big deal but we want it fixed and the engine light to go off. The dealer is giving us the runaround, or at least I think so.

I bought a 1999 f350 v10 about a month ago took it on a 1200 mile trip from Arizona to Kansas. Truck ran great till I got Kansas. The truck started to lope after I got fuel at a fuel station. Did not get any check engine light on. I check for vacuum leaks did not find any. I change all the coil packs, spark plugs, IAC valve and fuel filter. Clean the intake and put sea foam in the fuel tank and the truck still idles rough. Change the egr vavle. Truck ran great till I got 10 miles down the road then the truck started to lope again. So I'm getting really frustrated over this truck.

I'm just a shade tree mechanic try to diagnose a hot crank no start condition on my 2006 F-350 6.0 that I purchased second hand about six months ago. I first took it to a diesel shop to have them fix it and the mechanic told me that the stand pipes and dummy plugs needed changing out but couldn't tell me 100% if that would fix the hot no start problem.. I have been reading a lot about this problem and it seems that the snap to connect fitting on the HPOP is the most common problem on these trucks. It seemed easy enough to do so I went after it only to find it was already replaced with the updated part.
I went ahead and changed it anyway but it obviously didn't work. So today I pressurized the system through the ICP port with my small harbor freight compressor up to 80 psi and forced the IPR valve closed with 12v. I then listened for a leak in the passenger side valve cover with a hose stuck in the oil fill cap, the driver side cover from some drain hole under the air filter housing and in the oil filter housing. I could hear a mild hissing from the driver side and the oil filter housing but it was clearly louder from the oil fill on the passenger side. This leads me to believe I have a top seal leak from one of the injectors on the passenger side, but not 100% sure. Should I be hearing anything at all from the driver side and from the oil filter housing if its a bad seal in the passenger side?
Another problem I just found out I have seems like maybe fuel in the oil. I done a oil change this week after 3500 miles since last change and drained out five gallons of oil!! The oil seemed really thin. My coolant level is still good so the only thing I can think of is fuel dilution. Could this possibly be the same o ring or injector that is causing my hpo leak or something else? Will a bubble or balloon test diagnose this?
I bought a cheap OBD2 reader that works on my Ipad with a app called Dashcommand so I can see what codes were stored. The codes are...
P0401- Exhaust Gas Recirculation A Flow Insufficient Detected (EGR has been deleted)
P0528-Fan Speed Sensor Circuit No Signal
P0670-Glow Plug Control Circuit/Open
P0683-Glow Plug Control Module to PCM Communication Circuit
P2290-Injection Control Pressure Too Low
So far my thoughts are to replace the injector and nipple cup seals to take care of the hpo leak. Once I have the valve cover off, clean the injectors real good and cycle the fuel pump with turning the key on and inspect the injectors for a fuel leak. Is there a better way than this?

I have a 2001 f350 v10 that has been giving me fits. has 88000 miles. cranks and starts when cold or fuel pressure is below 40 psi. SES light will flash when it stalls and fuel pressure goes from 30 while running to 40 and the fuel pump runs continuously when this happens and truck will not start. replaced crank sensor and fuel pump was changed about two months ago. if I relieve fuel pressure it will start and run for short time then stall and fuel pump stays on. all fuses are good. I am at a loss.

I'm gonna change plugs , hoses, belts and fuel filter on my 08V10. Hoping it works with the mpg.
Anything else I should look for or do? Is there anything I need to know about changing the fuel filter?
