DO NOT DRIVE YOUR CAR ANYMORE!

You need to start over and get that timing belt on right. If you don't have any marks on your crank pully, there's one on the sprocket on the crank where the timing belt connects.

Do you see the 4 marks on your crank pulley? 3 are very close and the center of the three is red, the 4th is to the right of the grouped three and it's white.

The White one is TDC and you need to use that to correctly install the timing belt.

You can completely ruin your motor if you have that thing on incorrectly. Please, be careful!
