The car had a dead battery for about 3 months. Before the battery was drained my leaving interior light on. The car had been driven 3 times a week. tThe battery was about 6yrs old, wouldnt take a charge enought to start. I recently replaced the battery, but while the engine turns over, spark plugs fire (checked with a timing light) but vehicle will not start. Is there anything I need to reset and how?
