Your engine has a separate coil for each cylinder/spark plug. Are they all weak? How did you determine the spark was weak? And is the weak spark causing a problem?
You're guessing at a cause, but haven't stated what the problem is. Post a new question and tell us what type of problem you're experiencing -- engine doesn't start/run, engine doesn't idle, poor performance, etc. Also include engine size and type in the question.

SOURCE: Weak Spark

Check the cable, replace it with another cable to see if it is the wire or the distributor. If the spark is the same with the other cable it is the connection from the cap. I would remove the cap to see if anything is in it of it is corroded. While you have the cap off, look on the inside of it for erosion or corrosion.

I need to remove the headlights from a 2011 hyundai genisis coupe

Go to Hyundai's web side and register your vehicle (by VIN number). Then you'll have access to shop manuals, wiring diagrams and Technical Service Bulletins.... Particularly, shop manuals... then you'll see how complete/incomplete they are.

98 dode ram wont crank no spark

May have no spark due to a bad crank sensor, which is responsible for spark when it gets a pulse through the cars' computer.
