    Hello everyone. It’s my first time posting on here, but I’ve been researching the heck out of this issue all day on the forum and other places. I figured a video would be the easiest way to start this so I recorded one and put it unlisted on YouTube but I can’t post it here since this is my first time posting.

    I started this whole process with the red triangle of death, and all of my other lights on. My 12 V battery showed that it needed to be charged but was still good and with all the research I did it showed I should replace the battery anyways and see what happens. I was able to run the codes yesterday at an AutoZone and I’ve got a couple codes for the O2 sensor, but I’ve already replaced that a while back, and I have the P0A93 code so I’m planning to replace that pump. I also have a P2238 code. I decided I would drive the car home after making one more stop and the vehicle died on the way to that one more stop. Stayed in N and would not go into D or R. If it sat for a few mins I could start and go but it would die shortly after accelerating. I replaced the 12 V battery and now I can’t start the vehicle. When I press the brake and hit the start button. The power light turns green but nothing changes on the dash or the display. If I push the button again, the power light turns orange and I get my check engine light on, but nothing else. I checked all of the fuses, checked all of the connections, make sure all of the grounds were good, checked power in the back and under the hood, and both were good. There’s no power to the OBDII port so I can’t even read any codes or anything now. Any help would be greatly appreciated! Thank you so much in advance.

    Double check the AM2 fuse again. It is located in the fuse box in the engine bay.
