Cold start issues.
Sorry, I originally posted this in an existing thread in the 6.0 forum. I thought I'd re post here to get some more help.
Boy am I glad I found this place.
OK I have a 2000 F-350. I bought it about a 9 months ago. Always fired right up and runs great. First time with a deisel truck. I have a deisel farm tractor but it's an old air cooled job so the difference in technology is about that of a bicycle and the space shhuttle so I need some help with my problem.
We've had some very cold weather here as most everyone in the northeast this winter. I had some issues with cold starts, as in the truck not starting untill I found out that I had a block heater but someone had cut the plug off. I replaced the plug and it was basically smooth sailing for a while. Then we had an extremely cold night a few weeks ago and when I went out in the morning the truck started right up but after a while died. I called AAA and they sent out a deisel guy. He got me going with a little ethanol and said that the Powerservices deisel additive I was using was crap and the best way to prevent this problem was to add 5 gallons of kerosene to the fuel. He said that the fuel lines had likely gelled up and that was my problem. The truck burned the warm fuel from the fuel filter and was getting no new fuel from the gelled lines. OK so I add the kerosene and was trouble free for a few weeks. Then last night the temp dropped to -25 with windchill. BTW I keep my truck outside cause I have nowhere to park it indoors. I went out in the morning and had to charge the batteries cause they were very borderline (replaced them today). Turned the truck over and it started right up. Then again, after a couple minutes same problem, it started chugging and died. I figured I was having frozen fuel lines again so I warmed them with a propane torch and after turning the truck over for quite a while with the accelerator pinned I got it going. (Yes, bad, I know but I can't be stranded here) Then later in the day it sat for about 3 hours while I was visiting a freind waiting for the batteries I ordered to be deliverd and same thing! It started much quicker though after the stall out and luckily my old batteries had enough juice left in them for one more start.
Any idea whats going on? From my experience with deisel engines it's simple, engine not ruinning means no fuel. Like I said though my experience is limited to an old tractor, which BTW starts every time even when it's really cold and runs without issues. I stopped by my local Ford dealer who sells a ton of these trucks and he gave me a whole list of possible problems. I'm a sheep farmer and not what you would call wealthy so I'm trying to avoid paying hundreds of dollars only to find out they couldn't find anything wrong.
I guess I should tell you that I reprogrammed the computer with a Superchips programmer to performance mode too. Dealer said that it could be the problem.
One more thing, I also saw a post about exaust whistle. Is that the hissing sound the truck does once in a while while idling and or taking off momentarily before RPMs pick up, accompanied by a little lag? What causes this and is it a reason for concern?
Sorry for the long winded post guys and thanks in advance.
