power to the coil? if so odds are it's your coil. If not, not sure off hand. Would have to look at it.

Check to see if the timing chain broke, take out the spark plugs and do a compression test. You can turn it over with the starter and hear and feel the compression coming out of the spark plug holes instead of using a compression gauge. That should tell you if the chain broke.
Or you can lift the rocker cover to see if the rockers move when you turn it over.

Whats the fuel pressure like? Will it run on starting fluid? You may just have an Inertia switch that has tripped and shut off the fuel pump. Were all of these replacement parts done because it did not start or was it running before you changed parts?

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.
