Hi, I have a 08 G37S with approx. 108k miles. I just replaced the valve cover gaskets, and now the car wont start. 1 thing I did not do, which I wish I had, I did not disconnect the battery before starting this job. Why? Idk, just didnt. So now I have everything back together and the car wont start. The car has power, everything comes on as normal in Accessory Mode, but when I go to start it, It tries to kick over like it wants to, but just wont. Any Ideas? Im just a gal at home who doesnt like to be taken advantage of shops who say, you cant do it on your own. I dont have any fancy computer gadgets to plug in, if I need one, can I buy it somewhere? if so, where? Any help is appreciated.
