Well if your getting good fuel, the asd relay is okay as it support both fuel and spark functions. IF it was the "black box" (ignition coil) where the wires go to, it would somewhat want to start as there are 2 coils there. Each one controls two cylinders. So if you checked one cylinder, you will need to check one that coresponds to the other coil's cylinder. One coil supports the 1 & 4, and the othe is for the 2 & 3 cylinders. Becareful with testing this system as you can hurt yourself with the volatage it puts out.
If all 4 cylinders are sparking, I would be suspicious of the camshaft position sensor and/or the crankshft position sensor.
