Hello my name is***** am a Master Technician and I am glad to help you. Sorry no one has helped you with this yet.

Have you checked for voltage at the fuel pump?

Customer reply replied 2 months ago
No because when I initially turn the key I get fuel to the injecter. It will start and run but only for about 5 seconds. Then when I try again it will not start. This leads me to believe that it is a relay or saftey switch. My problem is I can not find this relay nor safety switch. And everytime I google it each site tells me something different. This is why I am asking a Nissan mechanic.

H​ello I have repaired over 30000 vehicles in my career and I need to ask you questions since I am not there in person to gather facts, data, or to test your vehicle. I may ask you to perform testing in my stead. If testing is needed and you would rather not perform testing I can give my best advice.

Does vehicle have security system? Factory or aftermarket? Do you have a voltmeter or testlight?

Eric yes it does have a factory security system. I think i have a voltmeter somewhere. Here is the problem. Would my fuel pump prime if it wasn't getting electricity? And if not, where is the safety switch or relay on this car?
I know that they place in a different spot on every car. And why can't any of you answer this question?

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
