Car will start then cut off, sometimes stays on a little while the. Cut off. We have checked the relay switch, and the fuel pump hums, and we can not figure out what is causing this. Please help!
Thank you Brad

Check the fuel pressure if its within specs and also try cleaning out the idle air control valve with a carb cleaner and see what happens
