A good way of diagnosing a problem like that is to remember you need 3 things to run an engine. Fuel, air, and a spark. Make sure the engine is getting gas. Make sure the spark plugs are firing. Make sure your engine is getting air. By working your way through those areas, you'll likely find the problem.
I have a 1996 ford escort that will not start and it has a new starter on it and a new battery in it but it still will not start
Check fuel. plugs, battery, wires
Often cars that are parked overnight need to be recharged. It is possible that the battery has died and needs a replacement or a jump to start.
There could be several reasons why a 1997 Ford Escort will not start. A few reasons could be the starter, the battery, spark plugs and wires, or even a blown engine.
Does it turn over? Does it have spark? Does it have fuel?
Start with the fuel pump. I have found in purchasing vehicles that have been parked for any length of time that I had always had to replace the fuel pump, strainer and filter.

The battery, cables and starter may be bad.
Bad starter Bad battery Bad connection on battery cables. Faulty ignition switch
either something shorted in the computer when re-connecting, or your grammar implies that you are trying to start it with no battery...which obviously would mean you should first re-connect the battery
some times you have to reset the computer.
MY XK8 WAS IN THE GARAGE FOR ABOUT 7 WEEKS AND THE BATTERY WOULD NOT START THE CAR BUT EVERYTHING ELSE CAME ON.
