Check the fuel pressure. A slight dip in pressure will keep the engine from starting. When is the last time you did a tune up? Even if you are getting some spark you might not have enough. New plugs, wires, distr. cap could solve this problem. Or try a new fuel filter. When diagnosing a car problem always do simple cheap things first, as this usually ends up being the cause.
Check the condition of the spark plugs and possibly the gap of the valves. A common problem is the spark and fuel will make it to the engine but loss of valve gap, bad spark plugs or even a weak spark will cause this.

My car problem started 3 days ago, it started with my Toyota security light blinking red, then a key like symbol on ...
you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.
your timing belt may have snapped!! When this happens, there is no compression preventing the engine to start up. Because there is no compression, the engine spines easily. Remove upper timing belt cover and inspect the belt. If broken, replace the water pump belt and tensioner pulley $400-$650 job!!
sounds like a broken timing belt,timing belts like to break during engine cranking and engine shut down. there are inspection holes in the timing cover,if you can't determine, remove top half of timing cover and check belt for slap,if there's slap,it's broke.
