Cold start issues, which fluid needs a heater?

[TSO]

Could depend on how/where it was sitting; if the lines/filter were exposed to wind the freezing effect could have been significant. Changing the filter out by itself could help track back to cause. The filter is meant to allow water to fall and keep particulate matter out. BUT, if the filter is water saturated from condensate freezing then fuel can't pass and you won't get her to start. I doubt it's bad fuel so much as the right conditions to make the filter impassible until heat was applied. JMHO.

She always sleeps in the barn. Now, the barn is unheated and the last few nights have been in the double digits negative, but no wind blows on my girl!

I didn't have a chance to call the dealership today, nor did I go outside to try to start her up or the fuel filter. Hopefully I will have time to do both tomorrow.

As far as the fuel goes, the price difference is not that much between offroad, and green, I don't put that many hours on mine, so I make sure my supply is deleted at winter time, and buy green from a station that sells a lot of it to make sure I am getting winter diesel, then I treat it with Hows lubricator (Cheap and effective).

You could have leftover summer red if they don't sell alot of it???:confused3:

When you are talking -15 you are really talking about more than fuel additives are capable of reliably working. We had -35 yesterday. Our JD 6230 feeding tractor started fine. Block heater is plugged continuously except when the engine is running. Diesel is straight #1, no blend, no additives. It's not had a fuel related starting issue since we got it 2 years ago. Last winter we had many mornings in the -35 to -45 range. That tractor runs on straight #1 from mid-October through March.

Our L5740 is used only for snow clean-up and sits in a heated garage. Never had a problem. Never had an additive.

My RTV uses the same #2 fuel as the L5740 and today I needed to use it. Warm spell, was up to 10 when I started it but it was really cold soaked yesterday when the low was -35 and high was -8. It has Power Service 911 in its tank at a slightly higher than recommended concentration. It started after 3 heating the blow plugs cycle and seemed to run okay, but when I finished my task of moving trailers around, I drove out to the mailbox(200 yards). By the time I hot there it was sputtering - symptom of filter starting to block. I nursed it back to its home in the machine shed.

So my conclusion is #1 diesel good to very cold although fuel usage goes up dramatically. #2 with cold flow additive will get a person by some places but not in real cold. By the way way on my way home from town yesterday I met one of my neighbors with a Duramax stopped along the road. Running fuel from the pumps marked #2 with cold flow additive and his problem was gelling. A problem this year is it has been unusually mild so pickup owners have been getting by with #2 with additive - it costs 40 cents less per gallon than #1 and gets 20% better fuel economy. Now that we had a cold day they are running into trouble. Another neighbor with a Powerstroke had the same thing happen and a highway patrolman told him he had 30 minutes to get his pickup off the road or he'd write him a ticket.

In my experience with diesel over the last 30+ years:

- the filter gels up first because that's where the greatest restriction is,
- avoid that happening by using winter diesel (if you're caught with summer fuel in the tank, cut with kerosene or drain it entirely),
- keep the tank topped up to minimize condensation,
- use a screened funnel when adding fuel,
- use a good anti-gel fuel treatment (I rely on Howes Lubricator),
- if at all possible, keep the entire engine warm by whatever means you have,
- as a last, last, last resort use ether, but use it very, very, very sparingly.

I learned all of this the hard way.

Adding potions and lotions to summer #2 diesel and performing sorcery is no substitute for winter diesel fuel.

finally warmed teporarily to 35 with wind chill at 30. tried tractor and craked over first attempt. Phew!!!!Finally. I am glad it wasn't another more serious issue.

Well, had a chance to change the filter today. There was some "gunky ice" chunks in the bowl. Cleaned it out, put it back on with a new filter, turned the ignition on (activating fuel pump) ... Fuel bowl filled right back up. Tried to start her, and same thing, no fuel getting to the injectors. I didn't need to start it today so I didn't bother heating it up to start it. But, that tells me that it is freezing somewhere after the fuel filter.

Ya,and some dirt.
I'd be thinking about getting my fuel from a different source.

If it was mine, I'd be wondering what it looked like if you took that new fuel filter off. I'd also cut the old filter apart to get an idea what it looked like inside.

I would try cracking open an injector line above the injector and see if cranking the engine delivers any fuel to the line/injector fitting. If not, when you've warmed up the IP and rest of the fuel area to a temp where fuel should be delivered to the injectors, without being hampered by a freezing condition, then there may be sediment or other foreign material that is blocking flow at the IP from reaching the injectors. If you're getting flow of fuel at the 'cracked' line fitting, but still no start, it's possible the injector nozzles are jammed with junk that past by the filter, IF it was completely plugged when you changed it. So cut open the filter, inspect it, and post back results.:thumbsup:
