Fuel pump won't engage unless key is cranked all the way on

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Sounds like your Pontiac Vibe has a bit of a stubborn streak. If your fuel pump only kicks in when the key is cranked all the way, it could be an issue with the ignition switch or the wiring leading to the fuel pump. When the key is in the "ON" position, the fuel pump should be primed, ready to start. But if that’s not happening, the switch might not be signaling properly until it’s in the "START" position. A faulty relay or a worn ignition switch could be causing this problem, too. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554.
