I am having a couple of issues with my 2004 Quest. The first problem is the van will not start on the first try. It will turn over and try to start but it just won’t. It will start on the second try. I am thinking that it might be the fuel pump but i have read where the ECM can cause this to happen. The second problem I have is that my drivers side door will not unlock on the first try when I use the key. I will put the key in and turn it but nothing happens. When I try it again right away it will unlock. Does the ECM control the door locks also? I have read that the ECM has been known to go out on the 2004 model. Any assistance anyone can give me would be greatly appreciated.
