starter replacement instructions please? - How to remote start?

If the remote start will not function then more then likely you have a door switch or hood switch that has failed and so the PCM thinks it is still open and it will not allow the remote start to function. So let's start with checking for codes using this guide:

However, if this all checks out, does the vehicle start properly using the key in the ignition switch?

We may have an issue with the starter so here is a couple guides on this:

I attached the process below on how to replace the starter if this proves out to be the issue. Thanks
