Car problem HELP!
 

OK so im getting to the chase here
i have a 1990 Nissan 300zx N/A
I have replaced almost ever thing imaginable in my car! except a new engine so it seems!
latey this has been happening like once ever 2 weeks or so
i will be driving and out of know were BAM the car just ..shuts off ( its an auto so its not me killing it)
it shuts off with out warning sometimes i dont even notice it until my steering wheel locks up! and the breaks dont work
wtf is wrong with it
its getting to the point of scary when it shuts off in the middle of the road sometimes freeway and i dont notice it.
when it shuts off it starts back up no problem when i turn it back on!
whats wrong here?

alternator on its way out? i don't know for sure though, could be a number of things.

I just put a new alt in 3 weeks ago along with getting the main wire from my alt to my battery rewire because it fried itsself
and also got a new alt belt lol

and its not throwing any codes?

Nope nothing
it just shuts off
no notice sometimes i dont even know it shuts off
no nothing no lights come on doesnt shift down or start to idle low just bam its off
but starts back up again no porb

BAM!
next thing u know the thing blows up

Oh god dont say that haha
thats just the next thing i totally need to happen to it hahah fricken eh

try checking the main relay. i had a similar problem in one of my cars a couple years ago and had to replace that.

the main relay isnt very common to fail, but its something to check. GL!

Thanks i will deff get that checked!

o2 sensor

I hope that was a joke.

It could be a wire grounding out.

(o________o)......

umm hmm maybe try coil packs? distributors? checkie fuel pump?

probably something electrical

maybe check all the electrical connections using one of those voltage check thingies

my old car, the main relay wire was too close to to something sharp and so over time, the wire eventually grinded to the point where yes, my car just shut off while i was driving. ignore the o2 sensor thing, i was thinking about my other old car.

i say something to do with the ignition cylinder

coils

I had the same problem before in my previous car.. it was my ignition column. If you've replaced everything under the hood, its worth a look.

Are you out of gas?

Sounds like my car when the fuel pump was on its way out... car would just die while I was sitting at a light... but the exhaust was so loud, you knew it wasn't running anymore...

Well she is blonde :P Look at it this way if it dies and doesn't kill you, you might get nuff money to get a TT!

DO NOT DRIVE THAT THING UNTIL IT'S FIXED! Not only do you put yourself at risk if it dies at random, you're putting everyone else on the road around you at risk as well. Since it's an auto and not a manual, you don't have the ability to restart the car until it's stopped.

My parents car had an issue like that at one point. It was a relay.

Your car is starting to sound like mine. I would seriously consider getting rid of it. From experience.. once you replace everything in the car.. then things you replaced just start breaking again.

Couldn't you put the shifter to neutral and start the car while you're still rolling?

Some automatics don't allow you to start in neutral, while those that do often have park/neutral safety switches that require the brake to be depressed while you start the car.

Main relay is a possible cause of this. Also I'm going to go out on a limb and since your a girl I'm going to guess your key chain weighs about 5 lbs with various shit dangling off it. This causes wear in the ignition cylinder and over time it wears out the tumblers. This causes the ignition to rotate due to the weight of the keys and sometimes results in the car turning off even though its still in the on position (I have had this happen personally so this is how I know)

Now when I see people with heavy key chains I tell them the only thing that should be attached to the ignition key is the alarm remote.

Might not be that but if I had to guess I would say main relay or what I described.

Berz out.

Check your AFM plug. Car wont run with the plug unplugged.

Could be the fuel pump dying...
