Not sure where you guys are getting your information (some bloke down the pub read it on the internet somewhere?), but in reality, it simply isn't true.
I even made a video to prove it, turn up the volume, wouldn't want you to miss the fuel pump coming on:

You obviously had the CPS disconnected? All my advice is from first hand experience through my years of ownership.
Without doubt this is the sensor used to close the relay when the engine is running, but I had always believed they would not prime without it either, sure I remember Mark Shead said it once on here as well. Logically it does not make sense, as the CPS will not supply an input until the engine is running, so I may be wrong.
I know for a fact the prime is temperature related, as I have experimented with it before.

If it's running I don't see how this can be a bad CPS, to me this is more fuel related.
Are you able to describe more about how it runs?
