After warming up our L3300, we went to put it in gear and it died. Went to crank it back up and all it did was turn over. Sounded like it wanted to start, but wouldn't catch. We checked the fuel and changed the filter just to make sure it wasn't a restriction or dirty filter. Fuel flow strong through the filter housing. We bled the bleeder valve and closed it back. Still not catching. I cracked the injector nuts at the top of the injector pump and the fuel barely trickled out the top of each line when the engine was turned over. Not a lot of experience with this tractor, so looking for next steps advice if anyone is up for another challange.
