The coil should have a constant 12+ once the ignition is on, this will be your spark problem.
S2 Fuel Pump relay will not work on a S1 loom, I dont know the specifics but I do know you'll need a S1 relay, and is probably why the pump is not priming.

You can use the S2 Ignition (silver) ECU on the S1 loom but you'll need a S1 Fuel (black) ECU or your throttle position sensor will not work.

Karlos!
