I have a 2005 CRV. It won't start sometimes. Today it was idling with the headlights on and after turning off the lights and engine it wouldn't start again, we had to get it jumped. Only the dash lights blinked the engine wouldn't turn over. It has done this on several occasions under similar circumstances with the same starting symptoms.
Then there are times when it starts fine in the same situation.
We had the battery, alt and starter tested and all tested fine.
