Plowing a couple weeks ago and all of a sudden the engine shut down. Still had lights and heat going in the cab with the key forward. Went to crank engine and it cranked but wouldn't fire. Got out and saw that the actuator for the fuel rail was in the closed position. got a strap and tied it open and it fired right up. Been starting the engine like this until I finally got a chance to pull it in the garage last week. I have no power going to the actuator with the key on or just bumping the engine over. All fuses are good. I checked all the diodes by using a new one and replacing each one, one at a time. I am not exactly sure if I am even in the right spot. Last time I had a similar problem it ended up being the switch in the left battery box. But when that failed, the engine wouldn't even turn over. Any suggestions?

BAD5oh, What is the serial number and dash number of the machine. Could it be neutral start switch?
