1. Hey Fellas
A guy on our crew ran our 2004 Cat 924G Loader out of gas and now I can't get it started. I have bled the fuel lines up to the injectors and still nothing. Theres no smoke from the exhaust. Any thoughts?
2. I do mean diesel of course and the filters were just replaced. I have cracked all the lines at the injectors and there was fuel squirting out of each. Thats why i don't understand why it wont start up. A friend suggested that there might be air still in the pump and that it will push fuel but wont have the pressure to open the injectors. I have gone through the simple solutions and now I am wondering where I should go from here.
3. allright guys I have tighted all lines to make sure there is no air leaking in i have drained the water separator i even used a little wd-40 to help out. i bled the lines up to to injectors and i am getting white smoke while i crank the engine but its not firing up. With all the suggestions you have given is there anything else i could do. I also covered the exhaust to see if it was a compression thing.
4. ill keep trying with the wd-40 but i thought i was spraying enough and im not sure about the fuel shut off but i dont think thats the problem if i was getting fuel to the injectors.
5. i am spraying directly into the intake with out the filters and i have it hooked up to another vehical for plenty of cranking power. But your saying i should spray a whole can into it
6. so i used almost the whole can and still nothin. Im about to give up.
7. ok so thanks for all the either points of view personally if you need a little extra help starting an enigine i'm not against it. but i'm thinking that air in the fuel is no longer the problem. i mean it doesnt take days on end to bleed a system. does anyone have some other iteas as to why this thing won't fire up

WD-40's main ingredients, according to U.S. Material Safety Data Sheet information, are:
50%: Stoddard solvent (i.e., mineral spirits -- primarily hexane, somewhat similar to kerosene)
25%: Liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
15+%: Mineral oil (light lubricating oil)
10-%: Inert ingredients
The German version of the mandatory EU safety sheet lists the following safety relevant ingredients:
60-80%: Heavy Naphtha (petroleum product), hydrogen treated
1-5%: Carbon dioxide

In my post to your first question was:
I agree. In the mid 1970's I had an International Harvester 464 diesel here in Michigan. It came with an ether can installed which sprayed directly into the intake manifold. The instructions in the manual said to make sure to have the engine turning over before spraying the ether. I never had any problem.
I did see problems when I worked in the machine shop rebuilding engines. There were bent parts. The key is to have the engine turning over when spraying ether, and it doesn't take a lot of ether.
I also agree with a previous post, take it to the dealer, chances are they can make a house call real cheap.

In your sixth post you said you've used almost a whole can of WD40. Did you use the new WD40 with the drop down straw and CO2 as a propellant, or did you use the older WD40 with propane as a propellant? WD40 is not flammable, nor is CO2. Diesels started from the shot of propane in the WD40.
In your seventh post you said you weren't averse to the extra help, I assume the extra help is ether--did you try ether using the method in my previous post to you?
Also, all the latter posts after your seventh post about mechanical problems-- I worked in a machine shop which rebuilt engines. I tore apart many engines that the owner said it just ran out of gas, but my gas tank was full. I would take it apart, and the oil pan would be full of new oil, and metal shavings from rod and main bearings. They would also say that their battery went dead all of a sudden because it wouldn't turn over the engine.
When rod bearings go bad they act like they ran out of gas, and the engine won't turn over with a fully charged battery. I saw this happen with my 101 IH combine in 1975, and my 1988 Chevrolet Caprice in 2001.
I also suggested calling the Caterpillar dealer for a service call. If the dealer's service department can't solve it, they can call the factory's service department. I've had to call the factory service departments before, and I've visited factory service departments for training seminars, some up to a week long. Unfortunately not Caterpillar.
It would seem like you've wasted more time and money so far than a visit from the dealer would cost.
Just some ideas...

it is possible to have a holed piston but unusual for one to go and the rest not at least fire and carry the lazy cyl. Just to toss in different thought have you pulled the rocker cover to see if you haven't got a broken camshaft
