Hello im new to this but i have a 2001 land rover disco. And dont start i just replaced the starter thinking that was it and batterie . It sometimes cranks and turns on normal but after 20 time i try turning it on. So i can actually turn it on with a dcrewdriver like nothing so idk if its a relay because all my fuses are good help

 

I know what is wrong, it is lack of Websters Dictionary...

 

Hahaha that's funny

It is probably the crank position sensor if all of your battery and starter connections are good. Check the connections then use electronics cleaner to get any grime out of the connector to your crank sensor. If it persists, I'd get a new crank sensor and keep the tools handy to swap it out because when it fails you absolutely do not start.
