I made the stupidest automotive mistake ever yesterday. I think everyone would enjoy the story. Especially if anyone runs into the same problem I did. Long story short, I had to mess with the LPFP for a couple reasons, one my fuel gauge wasn't working since I've done the LPFP, and two I thought the seal between the tank and the green hat was leaking.
Because I was frustrated and wanted to get it figured out asap, I threw the back seat on the roof of the car and didn't open my garage or any windows. First mistake of the day. After messing around testing resistance from the fuel level sensor, I finally concluded the wiring and the sensor itself is good. I checked for codes and the car was saying "resistance is too high". Weird. After farting around with the sensor I finally realized it's the position you put it back in which is the problem. If you put the LPFP basket back in at an incorrect angle, the lever on the sensor gets hung up and stuck. It gets stuck in such a position that the car knows immediately somethings wrong once it's hooked up. After I made this realization I put everything back in, made sure the lever was free and not hung up, and connected everything back up and boom I now see my fuel level.
I open my garage, pull the car out and take it for a quick test drive to make sure everything is OK. I turn down on the busy 5 lane road by house and get on it. As I get on it, I see a lady walking on the sidewalk looking at my car as if it were on fire or something. I think to myself "haha it must be the noises the car is making while accelerating thats triggering her". Not a moment later, I hear a loud thud, and then in my rear view mirror, I see my rear seat flying 50 feet in the air and crashing down in the road into oncoming traffic. I forgot it on my roof.
