How Much voltage have you got?
Will it bump start?
I was having starting issues before last Xmas, it'd start cold, but once warm wouldn't restart.
Ended up putting a starter rebuild kit thru it. She spun up much quicker and stronger after that.
Then a month or so later I'd experience more intermittent starting issues, where pushing the starter button would result in anything from a click, to a start, to almost a start, to just nothing.
I ended up challenging one of the diesel fitters at work to solve it one night. He went thru and checked every wire, and then pulled apart the starter switch block. There we found the contacts of the starter button somewhat heavily corroded.
He cleaned off the corrosion with emery cloth, applied some lithium grease? And retried the starter - fired first time after that. Reassembled, it has been fine ever since.
