Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started!

but I am home right now and scanner is at the shop. My thoughts were that the fuel pump was not running long enough to build up pressure or it loosing pressure on first start up. It seems to start all right after first start
Nissan Mechanic: Mechanic01, ASE Certified Technician replied 8 months ago

Ill be on tomorrow, if you want to do the code scan and im assuming you have a fuel pressure kit if you suspect the fuel is an issue I would check that too, you would want 51 psi on that to operate correctly, and while your there take a fuel sample just for piece of mind

Please let me know if you have any further questions.
Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Shawn.

What Customers are Saying:

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!
