make sure you have the right fuel pump. Aotozone sold me the wrong one and I had the same problem. two fuel pumps will fit but they have different pressure settings. One is for throttle body and one is for multiport. I had a garage put the right one on and now it starts. I have another issue but at least I can drive it. I hope this helps you out.
