Help! My Z won't start...
 

... and I'm late for work!!

At first it started to turn over slowly, then seemed to die out. Now it wont turn over at all...

The lights, radio, etc work when the key is in the on position but when I turn it to start the car everything goes off... and then comes back on when I bring the key back to the on position...

No fluids under the car... nothing suspect or loose under the hood except a really dirty pop charger...

Is it possible I could have a dead battery even though the accessories turn on... maybe not enough juice to turn the starter? Im hoping thats what it is because if not then its probably my starter.... or maybe the fuel pump? Anyone got any ideas for me?

Thanks!!!!!

Sounds like you might have a weak battery, if it was a bad starter it probably wouldn't try to turn over at all.

+2 on battery

Battery

Def a dead battery with just enough juice left to keep dash lights on.

Ding Ding Ding... you are all right... thanks guys.

Ive never had a battery die before and still have accessories work.. .they've just always been dead. I took it into pep boys and they tried to charge the battery... then told me it was bad and wouldnt charge....

So now Ive got a bosch battery... didnt really feel an optima was worth the money...

thanks for the responses... thats why I love my350z.com!

crank sensor can cause the same symptoms for info for others...if its weak and can't be jumped its the sensor

okay so the new battery has been in for about 5 days and I've got a new problem... tonight when I tried to start my car it sputtered, the revs dropped off and it died... I tried again, same thing... .then I tried again... revved it as it started and it sprang to life.... then did the same thing again later tonight... had to rev it to get it going.... what could this be?

Could it be a fuel filter? Fuel pump? REALLY dirty air filter (im thinking from the ash because of all the fires)? What would make it do that?

bad alternator, which would also explain your previous dead battery, had the same problem with my old truck

really... hadn't even thought about the alternator... what will one of those cost me?

your best bet is to have it refurbished

refurbished? Can I just buy a refurbished one? My Z is my daily driver I need something I can get fixed today!

First thing is go to autozone(its free) or one of the place,s around you that will do a charging system test.Watch when they do the test and note what the voltage is and the amperage is.If you see anywere from 13.9 to 14.6 volts with an amperage of around 80-100 amps(depends on the load on the system) under load the alternator is good.

not for sure, most run around $300

well now about every other time I start it, it will either start just fine ... or the revs will drop to about 200 and it will sputter and then come back up to normal... wth is going on!! ....lol.

Are you throwing any codes?

Check the Air filter, MAF, TB, Fuel filter....

check the cranks sensor

thanks guys... looks like ive got a lot of work to do!

Let me know if you need any help...

As it turns out it was bad gas. I bought costco gas and after checking everything out and filling up with chevron it hasnt happened since. cool.
