A couple weeks ago my daughter hit a deer while going about 80MPH. She struck it on the front passenger headlight. No real obvious damage except to the headlight, grille, and timing cover. But from that moment the car wouldn't start. I read the codes and the two it gave were for the heated O2 sensor and camshaft position sensor. I replaced the camshaft position sensor, and it still gave the same code. So, I checked the crankshaft position sensor (no issues there), I checked for spark (again no issues after replacing all the plugs and wires), I checked the coil packs (all three are good). From there, I decided to check the timing. Since it wouldn't start, I had to check the timing belt and timing marks for the correct position. With the crankshaft timing mark lined up I found that the camshaft on the passenger side was off nine teeth. To fix it, I turned the engine by hand to TDC on #1 cylinder. Here's where things went crazy: The crankshaft timing mark no longer lined up with the timing mark. It was about a quarter turn off. So, I'm wondering if the crankshaft timing marks are made to where the engine is not at TDC on #1 cylinder? And, with the camshaft marks lined up, is the #1-cylinder exhaust valves supposed to be fully opened?

The exhaust valve should not be fully opened with the marks on TDC on #1. Here is a guide, look toward the bottom for the timing marks, I have also found the instructions and diagrams in AllData which are featured below.

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
