2006 350z pop charger/cat delete

so i this morning i tried to start my car didnt start figure it was the battery cause of the new amp i installed so i jumped the batter and when i went to start the car it idled like total crap sounded like hell.. when id give it gas it dies out making a weird hissing noise. my car port stank of gas while it was doing this.

i got the P0300 code along with a couple others P0130 and the typical cel light
p0429 p430.

im not 100% what the deal is the car is well maintained.

i unplugged the MAF to see if that was the issue it idled fine after i pulled it but once i wiped the codes out and tried to start the car it wont turn over all i get is a weird clicking a sound from somthing electronic in the car.

the amps unplugged and i tried to jump the car again still wont turn over..



has anyone had this or similar issue?

also i had a weird reading for the scanner saying the input voltage was to high or somthing like that not 100% was too pissed off to really care

 

Have you had the battery tested? you might have lost a cell. Something is definitely up with the battery.

 

im sure the battery is dead its been in the car 9 months and went threw a hell of a winter in kentucky and with the temps changing here in pa its gonna need to be replaced..i plan to replace it tomorrow but the only weird part was it wouldnt turn over even with another vehicle jumping it

 

^Normal. Replace battery and go from there with any other problems.

(LoL at "brutal Kentucky winter"!)

 

I'm guessing water leaked in thru the main harness boot over the ECU directly behind the battery, given you probably routed your amp wiring thru it...

 

ummm no.. its garage kept sooo i dont think rain has anything to due with my engine misfiring..

 

yeap....changed the battery but doesnt help with the error codes so..yeah

 

so ive come to the decision its not wet wiring harness like stated above but the battery was bad and i did lose a cell. i got the car going and i pulled the MAF sensor and it went into safe mode idling normal but a but a bit blurpy meaning its a bad MAF sensor.. hopefully a correct replacement will do the trick. and nothing is seriously wrong.. i had a feeling the maf was going out a month ago it starting throttling funny and idle a bit diffrent so kinda had a feeling it was on its way out.
