Well from my experience, It is supposed to come on for a second or two and prime your fuel system then shut off. Check to see if you have a leak somewhere maybe the injectors are leaking see if you can do a injector leak down. this is a quick check for you here I know it is a nissan forum i just searched fuel leak down test on line for you to help. See if that helps you any.:up:
