keep searching , try U-TOOB you'll find how to re set that mess , Apparently you need a memory saver when you disconnect the batt. I think it's basically a small 9 volt batt. plugged into the cigarette lighter

My 2003 did the exact same thing. I've replaced everything and it still will not start. It will run if I spray starting fluid > I found that they injectors are not pulsing and when I turn the key on the fuel pump will only run for about 1/10th of a sec. HELP !!!
