Mine did the exact same thing the problem is still a question.I had a diog done and dealer said it was timing.Among other problems i changed the timing belt water pump and both belts.turned the key and it fired right up.(after 3-4 secs)This is my prob now!! checked timing again and its right on!! I touch a screw driver to my comp disconnecting my battery.I bought an OB2 and it would not read anything ERROR is what it said.I dont know?the manual said there was a prolem with the connection between the OB2 and the comp. thats as far as I have gotten......
