If you let your battery sit while you did your engine work, then you likely have a discharged battery. Lead acid batteries self discharge 1% each day even disconnected. While discharging, lead sulphate collects on the plates and lead sulphate is an insulator. A fully sulphated battery is a door stop. You can determine the state of charge on your battery by measuring the no load battery terminal voltage (hood lights are ok). 12.0 and lower, discharged. 12.9 and higher , charged. The starter solenoid and the starter motor draw a lot of current and a discharged battery cannot supply it. Charge your battery with a battery charger for 24 hours.
