Car wont start in the rain

My 89 Grand Prix wont start whenever it rains. The ignition gets wet and it wont start until it dries, (sometimes for days.) IS it a leak or does it need a new ignition?

Hi, your disributer cap must be letting moisture in or it has a hair crack.
REplace it with a new one & also spray some sort of water repellent (WD40) onto the new cap inside & out.
Also smear some grease around the rim of the cap to stop mositure getting in.
This cured a VW that plagued us every time their was either rain or fog.
Also check you rotor arm as well for hair cracks or just replace it with a new one.

If i drive my car when it has been raining will the spark leads and coil get wet from the road and stop the car starting if there is a crack any where

The chances are that you either have porous plug leads or the coil pack is earthing out , a quick spray over them all with ignition sealer will prove the point temporarily

What would cause 1999 grand prix 3.1l not to start when wet

usually when a car wont start when wet it is because of faulty plug wires or ignition module(supplies spark to the spark plugs)or both
best way to be sure is to get a squirt bottle and on a dry day start it up. spray water on the plug wires and see if the engine boggs down or dies-then work your way to the ignition module.if none of that works-get an aerosol can of brake cleaner and start spraying around the intake manifold and the vacuum lines
you should find the problem
