Rough Start - Something Seems Wrong

TN370ZLC

Don't really know but it sounds like
it could be a sensor ..... maybe .

I just took my 2003 Sentra into the
dealer for the same thing that you
are describing. Hard starts and finally
stalling after driving all day and
letting it set for a couple of hours.

Replaced the fuel pump ($ 680). This
did not fix the problem. After doing my
own investigating on the internet, ....
it turned out to be the Crankshaft positioning
sensor ($ 187). I took it back to the
dealer and they replaced the sensor.

Car runs fine now . It is now fixed. Starts
up on the first turn of the key.

Let us know what it is .....

Zero610,

Not trying to steal your thread, I'm simply trying to see if you and I are having the same problem. Hence me posting the video for you to compare with your issue.

Thanks to everyone else for your posts, comments and suggestions.

Bob,

No problem about adding the info to the thread. I'm glad you got a video of the rough start. I've tried to do that a couple times and they never come out good.

Your start sounds exactly like mine does when I have the problem (still doesn't seem to be every time).

Just out of curiosity, what type of fuel do you use? Originally, I was using some cheap fuel from Kroger, Valero, etc (93 octane) - whatever was cheapest in my area. Someone previously said might be cheap fuel, so the past 2 fill ups have been with Chevron. I haven't had the problem since but can't say I've tried to start within the 1-3 hour window when it normally happened. I'm going to try again today.

Let me know what the dealer says with your video evidence. Thanks again.

Well I buy gas wherever I am when I need it. I don't have a specific station use use really. I always put 93 octane in though. I dropped the car off at the dealer again today. They watched the video and agreed something is wrong. They said they are going to call Nissan and show them the video. We will see if they can figure out the issue and go from there. I've never used arbitration or lemon law -- anyone have experience with an issue that the dealer cannot figure out?

Sensors or the vvel system something does not let it have a complete combustion i would really recommend for everyone 2 get like a com-sort of a ECU to ur laptop connection 2 see the read outs, in the end the car stats and runs fine then its not the pump this is what i personally think

Bob - any updates from the dealer?

bclarke22

Car is still at the dealer (this is day 6). They tried replacing the cars internal key coding system?? They called the next day and said that did not work...

So -- I'm still waiting. I wonder when they decide to give up?

I live in Florida so I'm dealing with heat on fairly regular basis...I always let my car cool down for about 30 sec...also it could be your battery?

bclarke22

No, they checked the battery early on in the process. It doesn't seem to be weather related now (high heat) -- it has cooled off considerably here. The dealer called this morning and stated they are considering replacing the fuel injectors now (they said they called Nissan about the issue). I'm not a mechanic -- but I feel that's heading in the right direction. I think it's combustion related (air, fuel or spark) or a sensor myself - but what do I know

I'm heading out of town for work for a week -- so hopefully its resolved by the time I get back.

I'll let you all know what's happening as soon as I hear.

Well - talked to the Dealer - they are now going to replace the fuel line and the ECM unit? I'm beginning to think they are just throwing parts at it now hoping to get lucky and find the cause. They think it'll be ready Monday -- 14 days in the shop now.

maybe you should call back to that place that AK pmed you about and just have them give you a new z instead lol

bclarke22

I think that's a good idea now - I have contacted the Virginia Consumer Affairs Dept. And according to the warranty booklet - I'm required to contact Nissan Consumer Affairs prior to enacting the "lemon law".

AK -- I'll take you up on your offer for the email address now.

Thanks

Picked up the 09 Nissan 370Z from the dealer, also brought in my other key for programming. They replaced a fuel line (causing the gasoline smell) and damper assembly; and also replaced something called the IPDM (Intelligent Power Distribution Module in the Engine Room). Nissan also filled the car with gasoline - note that they put nearly 200 miles on the car from the time I dropped it off - We shall see if this cured the issue.

Bob, I'm try to gather information about several anomalies that may or not be related. Prior to your failure, did you experience hesitation or lack of power when accelerating? I'm just wondering if you have any fuel pressure issues.

Thanks!
