John Deere won’t start

[lp51]

I have a JD 5205 that won’t turn over. Turned key on and jumped across solenoid and it turned over but didn’t start. Any suggestions.

Battery? Battery cable connections?

More details would help get you more accurate replies. Side note. You can't start that tractor by merely turning the key on and "jumping" the starter. It has a bypass relay that prevents ignition circuit voltage voltage from reaching the injection pump. (maybe you didn't know that)

Yep and that circuit has some known issues with a cold start thermistor that shorts, blows the fuse and won't start. Check all of your fuses.

Went out this morning to try it and I had left the switch on all night. Charged battery a while tried it and fired right up. Have started three times since and everything works fine. I’m sure the problem will show up again.

Or it hopefully won't
