Hello I have a 1992 honda accord 4 dr lx that will run fine when its has not rained the night before. My car has 334,115 miles on it but is in good shape. I pressured washed the engine awhile back and it would not start for awhile I guess I got something wet then we had a dry spell and it seems when it rains it will not crank it will turn over and sound like it will but it won't catch on. I can keep trying and after awhile it will try to catch on so I usually wait for it to set for several hrs to dry out and then it will eventually start please help thank you

Remove the distributor cap and allow it to completely dry out for 45 minutes. Then replace the cap, ensuring that the large 0-ring is properly installed. It's best to coat the 0-ring with silicone grease. Most Honda distributor caps are ventilated. If you have 60,000 miles on the distributor cap, I would replace it.

Most likely the distrubutor is the problem it probably has a crack or not seated 100%
