GM and GMC

Why would a 1995 GM van not start on damp days if you have already replaced ignition wires and the distributor cap?

It is possible the coil is arcing when moisture builds up on the surface of the coil body near the tower where the coil wire plugs in. on dry days no problem but with a little moisture on the surface of a surface that has oil or surface/material degragation the path presents enough conductivity to allow high voltage arcing. Just spray a light mist of water on the coil surface and it should happen. good luck
