If you're encountering an issue where the pump is showing "not available" while using the Exxon Mobil Rewards+ program, follow these steps to troubleshoot the problem:

1. Check Station Participation: Confirm that the Exxon or Mobil station you're at participates in the Exxon Mobil Rewards+ program. Not all locations are included, and if you're at a non-participating station, you won't earn points or may experience issues using rewards - learn more.

2. Make Sure You’re Logged Into the Right Account: If you are using the app to redeem points or access rewards, ensure you are logged into the correct account that has your points. To verify this, you can log out and then log back in.

3. Use the Right Authorization Method: If you are using the pump but prompted for a PIN, ensure that you're entering the correct PIN associated with your Exxon Mobil Rewards+ account. This PIN is important to authorize your transaction when using just a phone number at the pump - learn more.
