Try replaceing starter relay with another of your relays. make sure they have the same part number on them if you switch them and it starts replace relay with new.

sorry cannot be more helpfull but there are many many reasons a car wont start

this doesnt make any sense wont start but it will turn over then u say it starts but wont kick over??? hmmmmm do u have gas in it?

What type of car and motor size and year?

Does your car have a security system on it could be enabled to not let car start

what do you mean by not turn on no power at all starter wont engage engine wont turn over or car wont start

bad battery or starter to start with if it wont turn the motor at all.

Sounds like you blew fuse. Fix fuse and borrow a car starting switch they use at car repair shops. As long as you can turn tumbler to on ,you can start using the starting switch from repair shop..There should be a way to run a start button to start car and your off/on key should be OK

If the chain broke yes the cam will not turn, only the crank will causing the fast spin

check battery connection. make sure terminals are clean. and make sure the terminals are not loose when connected
