Looks like your ECU (Engine Control Unit) is no good. You would need to replace OR reprogram it (better option) BUT before you could try a couple things that i have done and they seemed to help. Try 1) unplug positive battery terminal for about a minute or so and put it back and give her a go. 2) That's all i got hopefully someone else can give more insight on the issue on the upside you can find some on ebay for as little as $40
