Why????
 

So after a long trip to China for some work i got back home.
I unpacked and decided to take my supra out for drive but the car wouldn start.

I have checked all fuses, check if it has any voltage, we pushed to car in gear, checked if the starter was stuck but nothing wrong.....

Do you think the starter is shot?

its a '92 N/A 5 speed manual rebuilded last year in december but we didn do the starter or did not replaced it, the starter looked in good condition.

How much voltage due you have at the batt? Did you check for voltage at the starter when turning the key? Have you tried to jump it? I had a truck I used to have to pull the starter every couple day and spray it out with electrical cleaner if I didn't want to push start it. So cleaning it might help. Just wouldn't use anything but electrical cleaner.

it might have just gotten low because of your long trip. it happens...go for a long drive in it and thatll charge up the battery, then test it the next day to make sure.
