I have an L3901 4x4 gear-drive with just over 1000 hours that doesn’t want to start. It’s been going on about a month. When I turn the ignition, I hear the fuel pump kick in and two lights on the dashboard, but nothing else. No sound at all. If I switch the key off/on several times it will eventually try to start… a few more times then it starts up. Once going it operates fine.

I’ve checked all the safety switches, got a new battery and clutch a year ago, cleaned all connections, PTO is off, transmission in neutral, seat down, regular maintenance up to date, fuel is clean. I’m at wits end. I was thinking starter, but then saw the price and I’m hoping it might be something else. Any thoughts?

I'm gonna second worn ignition switch contacts, I could be way off base and it could still be a starter but that's my educated guess based on the info given

I’ll give that a try tomorrow. Many thanks.

… and I pulled down a copy of the WSM, so I’ll go through that too.

I would be looking very hard at the safety interlocks.
