  • Hello Jessica. Let me check if I can get more information. What model and year is your Toyota?

  • Based on the VIN you have a 2019 Land Cruiser. Did you preformed the ECM reprogram at the dealer? The P0453 code is for shomehitng else, and may not be related to the P0630 code.

  • It’s a 2007 Pontiac vibe, so it’s like the matrix. Thanks!

  • Unfortunately, other than reprogramming the PCM there no other problems setting the P0630 code.

    As far as I know the P0453 code is not related to the P0630 code, and neither of codes should cause a no start problem.

    I suggest checking other things, like fuel pressure or starter. Does the engine cranks?
