90 S-10 BLZ Won't Start

Need Help. I took out the no. 1 spark plug grounded it and crank it. I notice there was no spark being produce. Is it my ignition coil or my ECM?

check your ignition rotor

I already replaced the rotor and distributor cap. could it be the pick up coil?

do you have spark going to your rotor or cap? if not its proby the coil

Yesterday I replaced the spark plug wires and the spark plug. So the rotor, distributor cap, the spark plug wires and the spark plug are all new. The last thing I did was to test if there is any spark on the coil. I unplug the distributor side of the coil and set it close to a ground and still no spark. Could it be the ignition module or the pick up coil. Thanks for you reply by the way. Awesome picture.
