Ok guys first of all I want to thank you for taking some time out of your day to help me. Ok tomorrow I will take all the fuses out and check for corrision although I have already checked to make sure all were good with tester. The tractor is hydro if I forgot to say. I have already run a jumper cable straight from battery to a good engine ground and did same with positive straight to solenoid. I will try to run it straight to the small terminal fed by switch and see what happens. I was able to start tractor without sitting on seat before. Of course if I was running pto and got out of seat it would shut off. The 008 code is for throttle sensor which says Voltage signal out-of-range or not calibrated. Do not think that would have any effect on starter but not sure??? My e-mail is Removed Private email Thanks!!

Will it start with a screw driver? Jumping across solenoid. Try that. If so its the ignition, ignition wire or solenoid. That test will show battery cables are good.

Use PM, not personal emails, for obvious reasons....
The throttle sensor might control cranking, but if so it ought to eliminate it completely, not just hamper it's action.
This could be part of what needs to be fixed overall to make it run right once it starts; and probably getting your fuel gauge fixed, or your eyesight checked if the gauge is working currently.:)

Did it truly run out of fuel?
When it originally stopped did you try to start it and these symptoms were happening then? As in starter briefly engage but not turn over?
Did the engine stall and lock is what I am fishing for here.

Ok guys I ran a hot wire from the battery to the solenoid small terminal (feed by ignition) and the starter spun right over. I checked and cleaned all fuses and nothing. Im thinking my ignition switch?? And coyote your right I need to pay more attention to my fuel gage as it would have saved me alot of hassle. Maybe I need to find out where this throttle sensor is if you fellows think that may be the problem?

Put in a new ignition switch today and it still does not engage the starter. I can start it by jumping across the solenoid with the switch on. This is the hydro model and only safety switch is the pto that would prevent it from starting and its fine. When you engage starter with switch it just clicks. Im going to tap into ignition today and run a wire directly to solenoid to see what happens. Any ideas??
