when turned off fuel drains back to tank. to start must leave key on for a whole to get fuel to engine. How long have you had this problem? every time it sets for over an hour or so.

Fuel pump only runs for 2 seconds when key is turned on .. Leaving key ON doesn't help! Strongly suspect CTS (Coolant Temperature Sensor) readings are incorrect on COLD engine .. ECM uses the CTS readings to adjust fuel delivery .. Scan test with live data view while engine is COLD is recommended so CTS reading can be compared to ambient temperature .. Fuel pressure test should also be performed.
