So I have a 2001 V6 Honda Accord with about 162,000 miles on it. I recently had the alternator changed since it failed, but recently, I have had trouble starting the car (usually after driving about twenty to thirty minutes and stopping for groceries or something which takes about fifteen minutes). Usually if I wait anywhere between five to fifteen minutes, the car starts up like normal (sometimes it shakes a little). I noticed it happening about maybe a few times a year a few years ago, but now I'm seeing it happen maybe a few times a month. I had the ignition switch changed, but that did not solve anything and just the other day I had the main relay changed and stopped for a hair cut on my way home and again, it wouldn't start for a while (and it started shaking when I eventually got it to start until I started driving it). Does anyone have any other suggestions?
