well guys im still trying to figure out the problem. i played around with the maf connection but it didnt help. I have a feeling it has to do with air or cooling or something because it will start if you let it sit but it doesnt start if the engine is still hot. Im gonna bring it to the nissan dealer ship tommorow and see what they can do for me. Hopefully things will work out, ill let yall know what it was when i find out.
