First start with all the details:

2005 Crossfire Coupe NA M/T
118k miles
No performance mods

Yes, I did a search but no one seemed to have the same problem.

So yesterday I went out to leave the gym and tried cranking up the crossfire but to no avail. The car would turn over and sounded as it was attempting to crank. I went under the hood and checked the battery connections but they were tight with no issues. I then checked the spark plug wires and noticed one on the drivers side was a little loose. I pushed it back on as hard as I could and the car cranked right up. Does this sound normal? The car did show a crankshaft position sensor error but it doesn't make sense that the spark plug wire being loose would make the car start if it was a crankshaft position sensor, correct? I could be way off and it is time to change out the sensor, in which case that is fine, but don't want to unnecessarily change anything if having a loose spark plug wire can cause issues with cranking. Don't be too harsh if these are stupid questions.
