Yesterday on my way to work, my car was running just fine.. no problems that I was aware of... When I got off shift and ready to return home, I was having a hard time getting my car to start...and stay running, it was really running rough.. and stalled a few times.. Top speed on freeway was 45mph... on side roads..20mph... I got it home slow but sure... and checked the plugs and wires.. they seemed to be ok , however I did wipe the plugs as a just in case... I started it up, and she seemed to run ok... no problem starting at all... As I went to my second to my job.. it started.. but after driving, was running the same as it did before... I barely got to work.. when I was leaving again...I couldn't even get it to turn over.. it just wouldn't start at all. I had to pushed home. I have replaced the throttle position sensor a few months ago, and wires and plugs as well... I did a self code scanner check this morning and the KOEO code was 111. At this point my battery is dead, and I can not do any more until I get a jump.. Do you have any ideas as to what would causing this problem.. Any ideas would helpful.. Thank you

    i would have the fuel pressure checked. from yout description, it sounds like a fuel pump failure. you need a shop to check and verify.

    code 111 is a pass code which means the PCM is not detecting a failure. A lack of fuel could cause your issue, or a low vlotage issue. Due to the fact that it would not turn over it is likely you are dealing with a voltage issue. Check your battery connections and grounds, and if they look ok I suggest you get it diagnosed.
