Default ruff starts

ok ive run into some sort of problem. the other day my 89 bonne se sat for an extra day w/o driving(which doesnt happen very often) and ever since that day if my car sits for longer than say 3 hrs, its really hard to start the car. not a dead battery, and not an alternator. just had the fuel pump replaced a month ago. this really becomes a problem on rainy damp days, my friend(whos a mechanic) says i may want to replace my coilpack as there could be a crack and some humidity and condensation is leaking in a screwin it up, any ideas other than that?????!?! please help!

I'm having the same problem, but it is not limited to rainy/humid days. If it sits for a long period of time, my car takes 3 cranks to fire it up. I was told coil pack or ignition module

Not too faimliar with that problem in the coil packs but I do know if you get crack in your distributor cap and moisture gets in you will have a very similar problem so the same idea is there. Always a good place to start looking, especially since they take like 10min to pull. Clean them off and visually inspect them, also try twisting them different directions and see if a crack pops up. One of the more extreme ways to check would be simply dropping them in a bucket of water and check for bubbles. They should be fully sealed and if you see bubbles you need to replace them immediately anyway so I guess if you have the $ now you can try that. If you don't see bubbles dry them off and plop them back in. Heh just my crazy idea

I had to replace both the ICM and coil packs on my lesabre last year. Mine was different though, it would not restart after you shut it off if the engine was hot.
