Just got another g37 and I was trying to jump start the car in dark which obviously didnt go as planned. I mistakenly switched the terminals on the g37 from positive to negative and found out when the car was not starting.

Anyways so fixed it right away. Now when I press start button it cranks really lightly and everything turns off. It won't start even with a jump.

What is my next step should be to see? The fuse on the positive battery terminal seems fine

 

Your battery may be toast. Have you replaced it and tried to start the car?

 

Not yet will do so in the morning. Hopefully it is that... but the point that is killing me is that it won't even start with jump from Nissan Titan

 

also the fuses you might have toasted that too

 

Any specific fuses?

 

ouch... that mistake will really hurt in the financial department...
You might end up with a toasted ECU and other electronic modules...

 

I guess my jumpers werent good enough because borrowed other ones with battery attached started right up

Thanks

 

good to hear. So you're all set now?

 

Yes haha. Thanks
Got my worried

 

I'm glad it worked out for ya man

 

My wife did that once on our FX.
Reversing the jumpers toasted them.
The car started fine when somebody put a fresh set of jumpers on properly.

It's a miracle the battery didn't explode in somebody's face.

 

You should still look into getting a new battery.
