Default Bottomed out on a speed bump and car wont run now

I moved into this new neighborhood with huge speed bumps in it. I usually idle over them and even have to brake on my way down them. Last night, i went over one and did all that, but it wasnt enough. I bottomed something out on it and my car just died on me. I looked under it and there isnt any leaks or anything. It just starts up and dies. I need some help or info on this. Thanks

Rip an 02 sensor wire off? Smash a fuel line (might be able to build enough pressure to start, but can't deliver volume to stay running)

trace your fuel lines to make sure you didn't pinch one flat, sounds like what might have happened.

Just kid of a shot inthe dark here, but do our cars have a fuel pump safety switch on them. Like when there is an accident there is a switch that is triggered that kills the fuel pump so that fuel is not continually pumped out if the car is over turned or what have you.

might be something to look into.

do ypu hear the fuel pump prime when you first turn the key?

The pump is running, but do you have fuel pressure at the valve on the rail?

Did you possibly have a corroded ground strap, and the big bump finally ripped it off?

are your battery terminals really tight? The same thing happened to mine because my terminals just didnt quite connect right. I just tightened the negative and hasnt happened again since

Check your ignition relay and see if it didn't go bad at that time. Stranger things have happened.

Have you had someone check the codes? It might give you some insight into what was damaged.

Well if it ran with the carb cleaner it means it isnt getting fuel. Recheck all the fuel lines and wireing. It is something fuel related...
