well. it was a really hot day and everythings was allright with the car but when I arrived at my friend house it stalled right when I stopped. Then an hour later I decided to go but the car didn't start. starter was working strong but it did not start. I dont think it's related but my clutch is slipping a little bit if that help. oh yeah it's a 1991 240sx.
I don't know what I should check,

Thank you very much!!

 

Does your lights light up? Check engine light? Any power to the car?
