Engine stutters on start - no pattern to problem
 

I have a 2011 370z with 144K. My problem is the engine will stutter and skip when I am starting the engine - but this is very infrequent and unpredictable when it happens. At first, the stutter start showed up when the fuel tank was less than a 1/4 tank. On a full tank, or anything more than a half tank - the problem does not occur. Maybe that is coincidental. I was told to replace the coils - but that did not resolve the problem. I took the vehicle to the Nissan dealership. The diagnostic report showed it "might be" the fuel pump.
I have driven the vehicle for the past week - from a full tank of gas to a quarter tank of gas - without any "stutter start" problems. The check engine light has been on the entire time.
I am confused by this and am beginning to believe that it might not be the fuel pump. I would appreciate any input or suggestions this forum could provide. If you have questions - I will monitor this post every day and will reply promptly. Thanks in advance for your help.

Sound like your fuel pump hat may be broken. Only way to tell is to pull the fuel pump basket out and see what you see. CJ Motorsports offers a replacement for it.

Thanks spooler. I appreciate your suggestion.
