Hello everyone! I have a 2000 Honda Accord V6. Sometimes when I start my car, I turn the key and nothing happens. There is an audible buzzing coming from the engine. If I hold the key in the start position, the buzzing will continue and then changes to a loud grinding sound that skips for a few seconds and then the engine will crank and start. Sometimes, the car will crank right away when I turn the key, however the engine will sputter and take about 3-5 seconds to start. Once it starts, there is a rough idle.
This has literally stumped 3 mechanics. I even caved and brought it to a Honda dealer and they couldn’t figure it out.
I’ve recently (within last month) replaced: water pump, fuel pump, timing belt, battery, battery cable, spark plugs and ingnition relay.
Help!! What could this be?
