I have a John Deere 5055D that is about to drive me nuts. Here’s the chain of events. Went to start it last week (has been used several times this year) and it started to crank then went dead. The air filter sensor light came on the dash after that. Checked the fuses and my starter fuse was blown. Replaced it, and then I would get the starter firing but still it wouldn’t crank. I then tested the starter and thought I had a bad solenoid. I replaced the starter and solenoid and I’m getting the same thing.

After some reading I unplugged the cold start temp sensor because they cause some issues with starting on these models, but it produced no change. What am I missing here?

*Edit to add, it has a fresh battery from December.
