Problem with my '04 350z. Immediately after starting the car, about 2 seconds later the car shuts off, and then I have to restart it. It happened once last night and twice today already. Any clue what this could be?

Could it have anything to do with disconnecting the battery? A week ago I disconnected the battery because my CD player has not been working. I was told by several people to disconnect the battery to see if that might fix the CD player by "rebooting" it. That did not work, and now I have this problem.

Last Sunday I disconnected the battery and then only drove it like 15 miles or so the rest of the day and Monday. I went to Vegas on Tuesday morning and the car wasn't driven until yesterday (Saturday) morning. It didn't shut off Saturday morning when I start it and drove home from my friend's house, but then later that night when I went out, it happened. Then it did it twice today already (Sunday).

If anyone can help I would appreciate it. Thanks.

 

if it has an aftermarket ecu check the post start fuel enrichment, otherwise we need more symptoms.

 

How far away is your friends house? Does it only do it when the motor is warmed up? I had a similar issue - turned the throttle body wasn't opening/closing correctly (it was probably just dirty - this is what the dealership told me).. so i sourced out a used/fresh throttle body and then did "idle relearn" procedure.. no problems since.

Have someone take a look at that for you to make sure? I'm so used to older cars (like my '91 180sx)... virtually no electronics to worry about - when I got my Z33, it was driving me nuts...

good luck man...
