my vote is for your cps and i have proof! when the pcm comes on it checks the conditions of all the sensors. if any aren't up to snuff you will get a no bus. now the fact that you have a no bus with no start is resulting from the fact that the pcm is checking the cps. when it checks the cps and finds it is a dud the pcm will not energize the asd relay which in turn energizes the injectors and the fuel pump relay. the link below is from a different forum with two people that had the same problem. cps fixed it. click on the link and there is also a link in the link with another similiar situation. mike
