It's pouring gas like pouring from underneath the car while I was driving it. it just shut off and when I try to start it again that's when all the gas started pouring out. I noticed a lot of rough idling whenever I was driving it and now it won't start at all!

Good morning,

The fact you have a leak is telling me that is the reason it will not start. You need a specific pressure for the car to run. When you have a leak, the pressure drops to a point it will not allow the car to start.

Here is a guide on how to check that.

Do not try it again or try to start it. You have a huge risk for a fire. You need to find out where the leak is located and have it repaired.

If you cannot do it, have it towed to a shop for them to determine the source of the leak and give you a bid on the repairs.

Let me know if you have any other questions.
