03 6.0 F-350 manual tranny

Just changed fuel filters and FICM tested good.

One of our work trucks started acting up in the middle of pushing snow. The driver said that it started idling funny and almost acted like it was running on seven cylinders. And now the truck won't start at all. He pretty much described it just like everyone else in past threads, but is there anything else it could be, and is there a way to test it without having to remove it?

Forgot to mention that he filled the tank up and 3.5 hours later it started doing this. And it sit and idled for 2 hours in the cold and snow while everyone was taking a nap. This truck along with our others do idle more than they should.

 

Does it have the high idle mod? If not, you should install it.

I would pull the top filter to see if it is getting any fuel. Also open the drain at the HFCM to look for signs of gelled fuel.

Also, does it have the EGR system still active? If so, I would bet you that the valve is coked up.

For a "no start" you can disconnect the ICP to see if it will start with the default strategy.

 

I shoould have clarified that the truck will start but it only runs for about one second and then dies. It does not have the high idle mod, and I don't see it getting it for the simple fact that it is a county owned pickup and not a personally owned truck, so I don't see me getting permission for it. The top filter, can I just pull it out and turn the key to see if the bowl will fill with fuel? I drained the HFCM and no signs of gelled fuel. And yes the EGR system is still active, everything on the truck is how it came from the factory. How hard is it to unplug the ICP, to see if it is what is causing problems.

 

On the 06' the ICP is on the passenger valve cover towards the front, You can't miss it. Pull your EGR and clean it!! sounds as if it is ready.

 

if I read your post right you are talking about an 03 it is under the turbo, and I dont know how hard it would be to get to it. I would think that its not going to be easy. I would talk to your supervisor about the high idle mod and how important it is. I would think they would be ok with it. since it is a ford factory equiped option, and all you do is add the toggle switch for it to work. I did it to our trucks we had in the Army while I was in Iraq. Just told my supervisor and did it.

 

texans, top of post says 03'. Bottom says 06' I guess We got it covered!

 

Yeah the 06 is my personal truck and new to me. How bout we start this over and maybe with a better description of how the night went will help you guys help me. Sorry for the inconvenience we had been on the clock for 30 hours so I wasn't thinking real clear. After a few hours sleep I think this will help...

Truck: 03 F-350 6.0 Reg Cab 6 Speed with auxilery hydraulic clutch pump added for snow plow and scissor lift. Other than that bone stock, no mods of any sort.

Problem: Truck had been pushing snow for probably 12-14 hours and the driver let the fuel tank get pretty low (37 gallons added to a 40 gallon tank). After adding fuel he plowed for 45 minutes before pulling over and resting for 2 hours and letting the truck idle (our work trucks idle more than they should anyway). Then 45 minutes after taking off again he said that the truck started sounding like it was running on seven cylinders and then just a minute later it cleared up and it wouldn't be but a minute and it would do it again. Brought the truck back into the shop still not running right, turned it off, changed the top fuel filter first and then tried to start the truck to pull it out of the way until I got the HFCM filter changed. Truck would crank over and start like new, but after literally one second it would die. So I went ahead and changed the other filter, but the same outcome. Tested the FICM and checked all fuses and looks fine. Checked air filter...no moisture. No fuel gelling. Top fuel bowl was full of fuel. This is where I am now and I don't know where to start, any ideas are going to be much appreciated. I might add that two weeks ago, it threw a belt and the guy, just like me had never had to replace a belt on one of these so he had it in a million pieces, but the truck ran fine everyday until last night.

`I just went to the tech folder and read about the high idle mod and it said that it is not available for a manual tranny.

 

will it start after it cools down? like letting it sit over night and try to start it in the morning? If so you probably have a HPO leak. do you have any way of reading codes. that would go a long way in helping to get you suggestions on what to check.

 

I won't be able to check on it until tomorrow morning, I was going to try to start it when I got there to see if maybe something had just gotten wet, or like you said to let it cool down. I should have added that when we were removing the degas bottle the coolant was very warm in there, but the truck wasn't running hot on the gauge. No I don't have any way of checking codes, does Oreilly's carry anything that could check them?

 

The 03s had wire chafing issues with the injector harness.There are a couple studs that come out of the intake that are troublesome also the alternator area has a bad spot as does behind the egr valve and or fuel filter housing on some trucs depending on harness routing.

 

you really cant go by the factory coolant gauge. it's more of a glorified dummy light than any thing. By the time it starts to move of normal temp you are probably already way to hot. Autozone should be able to plug in and read codes, but if there is no cell on than chances are there reader wont see anything. If its a county truck why dont they just take it to ford and have them fix it?

 

If it gets to be something that I can't fix than we will take it to ford, but i guess they wanted to see if I could fix it before having it towed up there. Personally I would like to be able to fix it too. And it's cheaper for them to pay me than to pay for the tow and ford to fix it (which might have to happen anyway)

 

Sorry guys...fuel pump fuse was blown...should have been one of the first things checked.

 

Good Find, sometimes we forget about the simple things. But on engines this complicated and seemingly troublesome we often jump to something major.

 

I know I forgot what I tell other people...KISS...Keep It Simple Stupid.
