Why wont my car get a fire?

It has compression and the timing is right, but still doesnt get a fire. there is no fire going to the coils, so there is no spark at the plug. Yes the fuel pump works perfect and it has a full tank of gas.

If the engine has good compression, the only other 2 possibilities are lack of spark or lack of fuel. When you crank the engine do you have spark @ the spark plug? A quick check can be made with a ignition timing light. If there is spark while cranking the light will strobe.

I have the same problem but my cousin/my mechanic checked my car. He put the new timming belt and confirmed that the fuel pump had current/juice. I replaced crankshaft sensor and checked cam sensor and still the car did not have spark. Then after all this my cousin asked me to buy the Computer. I have already ordered the computer. However, My question is if I have look on programing the chip for the ignition KEY after I replaced the computer? Thanks
