Toyota estima emina problem starting

1. check your battery.
2. check your connection to the starter
3. check your ignition key.
4. check your relay, etc

Something must be wrong with your glow plugs or the connection to the glow plugs.

If your glow plugs are worn out you need to replace them.
If the connection is bad. you can hot wire your plugs directly but connecting a wire from the starter or battery to the plugs for 20 to 30 seconds then start the vehicle
