Car Stalls After Getting Gas

If your car sputters or dies right after filling up, the fuel system is likely struggling with vapor pressure.

Stalling after getting gas is a classic symptom of a faulty EVAP purge valve. When you fill your tank, fuel vapors build up and are normally stored in the charcoal canister. The purge valve releases those vapors into the engine in controlled amounts. If the valve is stuck open, it dumps too much vapor into the engine after a fill-up, flooding it and causing a stall. This often clears up after a minute or two of driving.

Another possibility is that you're topping off the tank past the first click of the nozzle. Overfilling can force liquid fuel into the charcoal canister, which is only designed for vapor. This saturates the canister and disrupts the EVAP system. In rarer cases, a failing fuel pump or clogged fuel filter can cause stalling after refueling because the change in tank pressure affects fuel delivery.
