After changing the pcv valve in my Mazda5 the car won't start.

All the lights turn on just not the starter. Does anyone have any ideas or suggestions how to troubleshoot this problem?

Hello! First I'm not clear from the statement; do you mean that now the car won't crank at all, or that it doesn't start up when it cranks? If the starter won't engage and crank the engine at all, check your battery connections, they could be lose or corroded. If the car cranks but fails to run, and the only thing you did was change the pcv valve, look to be sure it is installed correctly and that the vacuum lines you disconnected are now reconnected to there correct components. Would offer more in depth suggestions but would need more detailed information. Good luck to you!
