Default Starting issues on Cub Cadet 782D
I just bought a 782Dand it's the first time owning one. I bought it and the guy had the head off, so we put the head back on and got it ready to run. It won't run. We bled the fuel lines an injection pump and I have fuel, but it still won't run. Anybody have any ideas on how to get the thing running. Me an my Dad are about clueless to this cause we haven't messed with any diesel Cubs before.
Thanks Dylan

Bleed the fuel lines while cranking the engine at the INJECTORS.

is the shut off returning all the way? well there's only 3 things it needs. air, fuel and spark or in this case enough compression to ignite the fuel. I assume the air filters good? is the fuel any good? not contaminated with water? and I have to ask, did you use ether? not a good idea with glow plugs or intake heaters. that leaves you with compression? when you said it has good compression what are you comparing it to ? depending on the engine I've seen them range from 380 to 425 for a naturally aspirated engine at cranking speed.

The air filter is good it is brand new an the diesel fuel is good to no water or nothin like that. We don't have the air filter on it right now cause the previous owner took it off an we were more worried of gettin it runnin. I messed with it a little today an nothin I have good fuel to the injectors so my next guess would be to check the injectors to see if there good. If they are then I'm pretty well lost on this

You say you don't know anything about diesels, so I have some questions.

How do you "know" your getting good compression? Did you do a compression check? Or are you going by sound?
How do you "know" your glow plugs are working? Did you ohm them? Or pull them out and check them? How long are you cycling them?
Did you adjust the valves correctly?
Do you have the fuel injector lines on correctly? Are you sure? They can be crossed, I've done it.*
Is the pump in time?

*My bet, is this is the mistake.

Post a pic of your fuel lines. It's easier that way.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
