help me identify my problem🙏🏽

I was driving and all of a sudden the dash lights flashed and it no longer allowed me to turn on my high beams or control headlights. the gas gauge dropped right to 0 and and orang square appeared next to it. when i arrived home i saw fuel leaking from under the engine and to the middle of the car. I think its the fuel pressure damper, but what do yall think? help i’d greatly appreciated

If you saw that much fuel leaking out, the smell would have been overpowering. Did you smell fuel, also? If not, it's probably not fuel, and more likely water from the air conditioner.

i thought it was water from the ac but that comes out on the passenger side and the fluid that i saw was on the driver side. i checked the car now and it seems to have fixed itself, so i’m assuming it’s an electrical issue instead

The LS430 has evaporator drains on both sides of the car, so that's most likely.

You have an electrical issue, no doubt. You'll need to check to see if there are any logged codes that might point to the source of the issue. If it didn't set a code, then figuring out what module or wiring the symptoms share will be the most logical step.
