If you want your Rs to start, do the following.
1. Switch on the ignition and listen for the pump buzzing to prime the fuel lines.
If it buzz's, chances are the relay is ok.
2. Crank the engine and listen for the pump again buzzing. If its buzzing,your ok.
If not, then you could try another fuel pump relay(there are two different circuits inside the relay, one could be faulty).
3. If this does work, check for spark(I had the same problem with mine.No fuel pump or spark.)
Remove one plug and lead and hold it against the head and crank the engine.
You should see and hear the plug firing in front of you. If it does, its a problem on the fuel side only.
If the plug does not fire, its more the likely the distributor causing trouble.
Try plugging in a new distributor, switching on the ignition and spinning the distributor by hand. If you know see spark and hear the fuel pump for a second, you've found the problem. If not, you have some fault finding to do. Or it could also be something as simple as a jammed pump.

I had this problem with my S2 about a year ago. During cranking, the pump would not run(as it should) but when I by-passed the relay, it would work. At first I thought it was the relay(I was wrong). I found I had no spark so suspected the hall sensor in the dizzy as its how the Ecu knows the engine is cranking.If it fails, the engine will still crank but the Ecu will not will be able to see it cranking and so will not switch the pump or coil. I hope this helps.
