I put bad gas in my tank 2 gallons now my car wont start

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. If your Blazer only starts when you add gas directly to the intake, the fuel system might still be clogged from the bad gas. Start by checking the fuel filter, as bad fuel can clog it up quickly, cutting off fuel flow. Next, consider draining the fuel tank and flushing the fuel system, as even small amounts of contaminated fuel can affect performance. It's also worth checking the fuel injectors and pump to ensure fuel reaches the engine correctly. Sometimes, adding a fuel system cleaner to fresh gas can help dissolve residual contaminants, but since it's not starting on its own, a more thorough inspection may be needed. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
