Mitsubishi: eclipse not starting, battery 2, alternator

Question
91' eclipse 2.0 non-turbo. I've bought a new alternator & Optima battery in a previous inquire you told me to. Now my car will not start trys to turn over it clicks yet nothing. It started up no problems with a borrowed battery 2 weeks ago and moved the car in the parking lot, there has been no work done to it since, besides the brand-new optima battery which seems to work fine all lights come on when trying to start the engine brighter than ever.

Answer
If it's just clicking it's because the battery is low. This is because you bought it from old inventory and it has sat too long and need to be charged. I suggest jumping your car so as it get it started and then take a nice long drive without turning the engine off. Say like a 45 minute highway jont.
