car won't crank?

[Justin86]

For no reason lately the engine refuses to crank, put in a new starter and main relay and still nothing. Right after I put in the new stuff it wouldn't work then it started up all of sudden. Shut it down then an hour later it won't start, thinking its bad wiring in the harness or something. Checked all the fuses but I can't think of any other cause for this? I might try and just direct wire everything, toggle switch, push start, and new wiring and basicaly replace the main relay and ingnition system.

Any input is welcome.
