starting problem when wet

[pratman]

My car wont start in the morning when its covered in dew, or whenever a sprinkler sprays it. Its always above 70 here, so this is def a moisture problem. What do i need to replace. When its sunny and dry it starts fine.

One thing that comes to mind is maybe the dist. cap is getting wet. Next time it doesn't start, pop the cap and wipe out the inside and see if that helps.

Yeah, most definately check out your entire ignition system starting with the distributor. Moisture is somehow accumulating underneath the hood somewhere and seeping into your ignition components possibly.

Oh, and be sure to check the terminals on the battery for excessive corrosion while you are under there.

Take off the distributor cap and check the condition of the O-ring. I bet it is dry rotted and cracked. Change it and you should be fine.

Put on a new set of spark plug wires. When they get old the rubber insulation breaks down and moisture leaks through enough to effect the spark.
