The ignition module and crank sensor is the most common cause of a no spark issue but it would take some testing to be sure which one is causing the problem.

It was running but when it got damp out it would lose power . I looked under the hood that night and seen it was arcing , so I replaced the plugs and wires. It still lost power when it was damp out , so thats when i changed out the coil packs . now I dont even get a spark.

Are you sure you plugged the coils back in properly? Be sure you did not unplug and connectors to the module below the coils. How are you testing for spark?

I use a inline spark tester... All I did was pull the old pacs off one at a time and put the new ones on as i took the old ones off
Expert:  zzdaryl replied 5 years ago.
Did you check for spark on all of the coils? If so is there no spark on any of them?
Customer: replied 5 years ago.
no only one pack
Expert:  zzdaryl replied 5 years ago.
I would check the rest but my first answer still is the best answer I can give without some testing. The coils themselves will not all fail at one time so there must be a different problem, probably what ever was causing the initial problem finally failed(most likely the ignition module or crank sensor).

it was running ok till it got damp out thats why i changed the packs out and now nothing . So with new packs it would be a good idea to replace the ignition module as well?
Expert:  zzdaryl replied 5 years ago.
Its possible that would fix the problem but there is no way to be sure without testing. It is not a common practice to replace the module and coils at the same time but its worth a try if you can not do any testing. I would also check the fuses to be sure none got blown during the coil swap.
