I would start by spraying some brake clean or carb cleaner into the throttle body. Then try and start it. If it starts and runs for a couple of seconds you have a fuel delivery problem. (Check fuel pump, listen to hear if it turns on in the tank when you turn the key on.) If it does not start, you are looking at a timing, compression, spark, or air problem.
You performed a compression test, so we can rule out a compression problem.
I assum cause you are looking down the throttle body that you dont have an air delivery problem, so we can rule that out.
Unless any engine work requiring the removal and installation of engine components has been performed, you probably dont have a timing problem, so we can rule that out.
So, we are left with spark. Check to see if the plug wires are sparking when you turn over the motor. If not i would check the ignition coil, fuses, and wiring.
i hope this helps!
