I have been experiencing a intermittened problem with starting. When the key is turned to the on position, (not to start ) the dash board should go through a self test procedure. All the lights on the dash should flash, you should hear the fuel solenoid click, all lights go out and the unit is ready to start. What is happening is the only light that comes on is the glow plug, and the caution light. The solenoid does not click. A few hours will go by and then it will self test and everything is fine. I had JD come and get it, only to find that it would not fail then. For about two weeks now it has been fine. There is a computor board behind the dash, not sure if this is what is happening or not. Any one else had a problem like this or can shed some light on it. Thanks in advance.
