    Ok my lady friend's tractor is expierencing a 'tries to start/almost starts condition. She almost a decent half mechanic & claims she drained all diesel lines,cleaned injectors etc. She works nearly 24/7 so i don't even know brand name yet,just know it is a 50HP-ish,red in color, medium duty tractor. I'll be going over there one of these days to look,i think she has air in the line or a dirty filter..anything else i could use before my venture.

    I never worked on a diesel before,but her telling i can have her 1988 1/2 ton if i get it going is a hard to pass up deal!
    Of course all of YOU now know i NEED a '88 rear window AFTER that space debris smashed my other one :))

    Check the fuel filter air filter and electrical connections first. Then put some starting fluid to it if you have to.

    SLR, I'm not a diesel mech, but I have done alot of work on them. It does sound like air in a line some where. On some diesels,, there will be a primmer, some time it will look like a squeeze ball, others will just look like a little lever, about an inch long that should be connected to a fuel line, that you have to move up and down. It may take as many as 30 or 40 times doing the lever kind. If you check the fuel filter,( the kind that looks like a oil filter) make sure there is fuel in it, if not, add fuel to it. If you can find that fuel shut off solenoid, make sure it is working, turn the key on and that it moves to open the fuel shut off valve. There are a few other things you can check if these don't work, but you need tools for them.......one more thing, when you go to turn it over, make sure it has enough speed, cranking fast. I've seen old batteries and dirty connections that will get it turning but not enough amps to get starter turning fast enough.
    Hope these little tips and checks help......:drinkup:

    make sure it is primed...a lot of times in cold weather your diesel will turn over but never "catch", this is because it just isn't turning fast enough, especially if you crank a few times and nothing happens...you are wearing down the battery. you can try a little starter fluid first, but you'll have charge the battery....the quickest way to start a larger diesel with a jump start is to use two sets of jumper cables as opposed to one. when my IH 886 is slow starting i have to do it this way because 1 set of jumper cables doesn't deliver enough juice to get those big luggers running.

    if you can post a picture i can tell you what the tractor is and maybe be a little more of assistance

    I am still waiting on her to get back to me,she says she bought a new battery and it was trying to do it's start thing after it was hooked up. How many Cold-cranking-amps would be sufficient you guys figure for -15C type weather?

    -15C is like 5 degrees F ;) Is there a block heater or glow plugs ? Is there any way to warm the tractor up ? I'm hoping that you are going to tell us that she put anti jel in the diesel and a 5W type of oil in the crank case....
    For something that cold I really don't know what kind of CCAs you would need to fire that tractor up. But I would be going with the biggest battery I could fine in the CCAs for -15C
    I really think you need to warm that baby up some how, that may be your whole problem right there......

    if you can't get it to start, undo the injector lines where they go into the injectors, prime the system, then turn the engine over and :usflag:watch for fuel to spurt out of one, put bolt back in it and crank again till it comes out of another one, re-bolt it and conntinue till all are done.
