Said It Here

Why is my car hard to start after getting gas?

Filling up the gas tank floods the engine with excess fuel, creating an overly rich condition that causes the car to bog down or refuse to start normally. Drivers have to resort to holding down the gas pedal while cranking to clear the extra fuel before the vehicle will finally fire up and run smoothly.

“Every time I refuel, it does this crap. I’m suspecting an EVAP issue, and she smells like she’s running rich, but it isn’t throwing any codes.”source ↗

“She eventually fires up, but bogs down unless I give it a little throttle. Once I rev it a bit, everything clears up and she runs normally.”source ↗

“It doesn’t happen on every startup—only after I refuel. She eventually fires up if I floor the pedal while cranking, which I clear stops the injectors from injecting more fuel which fixes the overly rich condition.”source ↗

“Every time I fill this god forsaken car with gas, it refuses to start, and the only way it will start is it i hit the gas pedal and just keep it going for a couple seconds.”source ↗

“I tried to crank the engine a couple more times, but it wouldn't start. The cranking actually started to fade out and then stopped altogether.”source ↗

“Now when trying to start the engine.. I get clicks and no cranking at all. First it was louder clicks that got softer, and now faint.”source ↗
