The injectors are usually switched via a ground signal from the computer.
You can check with a noid light.
Try disconnecting the air mass meter, crank and see what happens. I don't even know if this car has one??
If you are getting spark it means the computer is getting a reference signal from the crank position sensor. Can you see an rpm signal at the tach while cranking?
Also check that the injectors have power and check the connection all the way back to the plug at the computer. You should do this before swapping computers because a short to ground to the computer will fry the injector driver.
If you are getting spark I seriously doubt it is a problem with the factory alarm.
Usually the injector harness has it's own connector to the main harness. Check the connections there.
I don't work on Mazda's but the principles should be the same.
