Car will crank but not start. No spark

We have had the ignition module checked, it is fine. Changed the crank sensor. Tried disconnecting battery and putting cables together to reset. When checking the ignition module we cleaned the connections and the car started and ran. But my son tried to move it and it died and would not start again. It has a theft chip below the drivers side dash, we have taken that out and put it back in. Nothing seems to help. It had been running fine until we replaced the batter because it had frozen solid. Since then we have had problems.

the only problem we had in the past was that when the car was driven for a distance, in the summer, it didn't want to take the gas right when we had stopped for a light and then tried to take off. We had to either give it a good push or tap the pedal until it took off.

Have already posted money on answers. Com and got the above suggestion, but they have now given up.
