I have had our 2007 FJ off the road and want to sell it, it is in very good shape and was very sound mechanically when it got parked in our yard when the plates were turned in. However just the other day I was unable to start it like normal (in the parked position) however when I shifted it into neutral it turned over. What would cause this to happen if it was just sitting and off the road? I want to fix whatever this is before selling it to someone. Never had this happen before so I am assuming it is only from being not driven and sitting in our yard. Any suggestions on what to look for or buy to fix this problem?
