It wouldn't start after sitting outside all night in the rain but did start in the afternoon. At first I thought there was water in the fuel so I added some dry gas but that didn't work. Same thing happened the next day. I have had this happen with an older model accord and found it was a cracked cap so changed the cap and then it wouldn't even start in the afternoon. My husband tried to jump it (why-I don't know, it would crank so I knew it wasn't the battery, plus the battery isn't even a year old) and now it cranks a couple of times and then dies a little. There's over 1/2 tank of gas and I haven't changed where I get gas from. It has about 125,000 miles on it. Any ideas?
