HUGE PROB, any advice appreciated

Hello Guys, I was on empty on my toyota corolla 05, got abt 5 dollars worth of gas, and then my car started sputtering after abt 15 mins, after which i went to a mechanic who suggested i put "HEET" in my tank because i must have gotten water in my tank. my tank was abt 1/3 full. car still sputtered, but i made it to my destination. i tried to restart my car after abt 4-5 hrs of it being parked and it sputtered, died, and the "engine," "oil," and "battery" lights came on. it was abt 1/4 tank full. i then had it towed to my dealer who said the possibilites are bad gas or diesel in a petrol car. he is saying that there is a possible 800-2000 dollar repair charge. does anyone have any insights into my situation? i would greatly appreciate any help!!!!!!

Better post this in the Corolla forum. Moved

Do not post in multiple threads. Read the guidelines.

You possibly may have contaminated fuel. Sometimes you can get away with draining the tank and running a couple cans of pressurized fuel injector cleaner through the injectors. You may have to replace injectors if that doesn't work. So the price can run up quick.

I suspect water in the fuel.....try a bottle of gas line anti-freeze in the tank. ISOPROPEL only
