However, I have power to door chime, dash. My headlights and radio comes on only if I turn my key back.

Hi,

I have a couple questions because this could be a few different things. First, are you certain the battery is charged? Is there a click or anything from the starter when you try starting it? Have you checked fuses and starter relay? Have you checked the starter?

Thank you for your reply and there is no click when I try to crank it, but I can hear the fuel pump sound.

Okay, we need to check a few things. First, we need to confirm the battery terminals are clean and tight and the battery is fully charged.

Next, I need you to check the fuses I highlighted in pic 1. Also, number 11 is the starter relay. I need you to either switch it with another relay with the same part number, or check it.

Here are links to help with checking the fuses and relay. Also, I added additional ones for checking electrical components.

If everything checks good there, we need to see if the starter is getting power to the smaller wire on the starter when the key is in the start position. You will need a helper to do this.

Here is a link that explains how to test the starter.

Now, if there is power to the smaller wire when you check, then the starter is bad. If there is no power, let me know and we will back track to see where power is lost.

Let me know what you find.
