Double check crankshaft timing mark, on your lower timing cover has some timing marks - crankshaft should be on the 0 mark. Camshaft timing marks--intake camshaft mark set at 3 o'clock and exhaust camshaft mark set a 9 o'clock. These timing marks are critical for motor to run and start correctly. These timings marks can move while trying to install the timing belt. After, you confirm or reset timing and belt, you can confirm timing is correct by rotating the crankshaft twice. Your timing marks should be on right on timing marks discussed at the top of the page. If timing marks are off, start over with timing process.
Hello! If the timing belt broke while the engine was running coupled with the fact that #1 cylinder has no compression; Yes, there is damage...Guru...Saailer
You either have the belt 180 degrees off. So you have to take belt off and turn crank only (slowly) around once to its mark again, but first you need to go to a website that lists motors that are called "interference fit" engines. (Think Gates belt co. has a list) If your motor is an interference fit then when belt broke the motor is trashed. Interference fit means that pistons can hit valves if the belt breaks. That is why they tell you to replace the timing belt before too long. Also if motor is interference fit when you try and turn crank go slow because you may bump into valve.
