car starts and then cuts out whilst dumping the fuel
Expert:  Matt replied 1 year ago.
Hellothe charcoal filter is there to capture fumes from the fuel tank and then release tehm back into the engine if its venting neat fuel then I'd say the filter cannister isn't being vented so check that the purge valve solenoid is functioning, this will be located on the engine and connected to the charcoal cannister

Expert:  Matt replied 1 year ago.
Hello the solenoid should not be live with the ignition, its only switched at certain times by the ECU with a running engineso that's worth checkingthough it sounds like its not being switched at all, and then overcoming the pressure relief valveso check the wiring loom for any signs of damage
