The battery and start was replace already.. I try locating the start system wiring diagram can’t find no where on line or location of the start relay location in the engine compartment. Need so help or any troubleshooting procedures

 

Check the stickies, there is a link with wiring diagrams. Check fuses and relays before you start throwing parts at it.

 

Always post the car details or we really can't help?
Year, model, engine, miles and what has been done.
