So its cranking? is there any smoke?
I'm not too sure what engine these run and how the fuel shut solenoid works on your engine but does it pull an arm when you are trying to start it? if you can manually hold it in place and get someone to crank the engine over and see if it starts. If it puffs white smoke while cranking you are getting fuel and it doesn't sound like fuel cut, if there is no smoke you may need to check for prime and check the fuel cut solenoid is working and has power.
Good luck!

From what you said , I would be sure the fuel system was primed up to the bleeder bolt at the injector pump , I would crack the injector tube nuts at the injectors and spin the motor to see if fuel is getting to the injectors , you say you changed the kill solinoid , are you getting voltage and a good ground to it ,there is a fuse and a relay to the solinoid , if fuel was present and still not starting I'd look to compression or possiblly a timing belt as that 864 might have a Duetz

It still sounds like a fuel shut off valve....
What engine are you running and how many hours?
If its a deutz it could have slipped the timing belt and bent your push rods (cheap to fix thankfully) It has happened!!! I can't remember how many hours before a timing belt change is required but it may be something to investigate.

i tried to turn it manually to see if there was compression it just turned freely so does that mean no compresion what can be the problem.

No compression could mean broken or slipped timing belt (if fitted). Remove your rocker cover and check your push rods. These are made to be weak so if something happens they will simply bend and not cause any damage to the pistons or valves.

Broken timing belt or bad fuel solenoid. With the fuel solenoid out of the loader the fuel will be turned on.
Look in the track machine forum and you will see a post from me on a broken timing belt on a T200(864).
