I have a ct335 hst had been moving some dirt for about two hours. Then when i hit forward pedal started to stall then hit reverse and same thing. So I turned it off and wouldn't restart for a few attempts then started and shut off instantly. Now it won't do anything. When I turn the key it makes one click I wait for the glow plug light to go off then turn the key and nothing. If I turn the key on and then push in brake before starting everytime I push the brake I get the click again. The sound is coming from the front of the motor on the right side if sitting on the tractor. This is my first diesel so I'm still learning but I think it's something to do with the fuel pump. When you step on the brake you can feel something engaging were the click is coming from. It has a small wire harness going into it. Any help would be appreciated it's still under warranty but the cost of the part might be less than getting it to the dealer.
