Ok I'm at my wits end new starter, alt, glow plugs, fuel filter,
I plug it in over night but if the weather is below 35 and the
Truck is left unplugged more than 3 hrs it won't start I'm sure it
Needs a new batt but a single moms budget won't allow that right
Now, today the temp was 3 deg and truck wouldn't start at all
Even being plugged in any ideas, yes I have been putting anti
Gel In the fuel

 

How does it crank can you see your tachnometer and see what RPMS it reads when you crank? does it try to fire at all?

The powerstrokes are a HEUI injection system. They rely on oil pressure to pop the injectors, and at those temps 15w-40 is realy thick and sometimes you just cant crank the engine fast enough to start it. Even though you are using anti gel fuel make sure with your fuel station that they are mixing there diesel and find out what kind of mixture also.

I would go and get your BATTS checked, and maybe try to find a way to get a light bulb to one of your batteries and see if they helps any.

I had fuel issues a couple of weeks ago, it turned out that the valleys biggest fuel provider had water in their fuel. It was getting to -30 those nights also.

 

turn the key on and leave on for 30 to 45 seconds before you try cranking the engine, The glow plugs might need to warm a little longer or might be going bad, the wait to start light is just a dummy light, the glow plugs will still heat even with the wait to start light off, until they reach a certian temp. Might just need to warm a little longer to get the fuel to fire. Could have glow plugs going bad.

 

Yes I plan on testing the batts in the mean time
Any ideas to get it to start and at least get it off the yard...

 

I hate to use this word..... But ether might be your best bet, battery charger on boost to help it crank faster. this damn 4 degree temp here in Iowa is not gonna help matters much though.

 

Ok finally got it started taking it to a buddies heated garage to again replace glow
Plugs after I have battery tested I used a 200 amp jump start to get it started

 

should be able to ohm test glowplugs to see if they are good, or hook them to battery one at a time while out and see if they get cherry red, if they are all good, might be glow plug relay or controller going bad as well.

If they all glow cherry red then they should be good and shouldent need to spend the money to replace them.

 

I guess the glow plugs on my truck are under the valve covers
Wich means I won't be able to do it today hopefully tomorrow

 

Good luck. It has been a bit brisk around here. My truck is parked for the winter but my VW TDI doesn't like it either. It it's below zero, I can get the water up to operating temp. Really need to get a cover on the front.
