My car had been sitting for the past week and I started it up last night, it ran fine for 5 minutes, the check engine light cam on and then ran out of gas. I put more gas in,cleared all codes, and now the bastard wont start up unless I pump the gas like its a carb engine, and when I get it started it idles at 350rpms, and will die after 1/2 a minute or so. Whats goin on. I also noticed that the upper radiator hose is leaking a little near the thermostat housing neck??? could this mean something......well im stumped here guy please help me out. Thanks
