Re: 2000 Accord Ex-Won't start when it's hot outside
Instead of replacing stuff *****-nilly, next time your car doesn't start pull the primary voltage feed from your distributor and see if it's getting 12v. (Don't pull the secondary and try to test that, as it's 20,000 volts but you knew that).
If your primary is getting the 12v, then I would consider replacing the ignition coils, but only then.
Keep a 10mm socket and a voltmeter in the car in preparation for testing this.
