Relay blown Clio11 1.9dti

Engine won't start, no warning and glowplug light Breakdown service diagnosed relay blown, towed home.
First question. do I have to remove relay box to get at relays, breakdown chap seemed to think so.
Second question. which is the pump and glow plug relays. Thanks.

The back story is that I gave someone a jump start and the red lead crocodile connector made contact with a metal part close to the battery as I was manipulating the jaws onto the terminal. This of course created a short with a flash of sparks. When I tried to start the engine there was a buzzing sound coming from the relay box and no red light on the dash or glow plug light.
Anyhow I've taken out all the relays one by one and found the one that is buzzing but when I swapped it for another identical relay the buzzing started again. This indicate to me that there is a fault in the feed to the relay. in the wiring or some other unit, maybe the inertia sensor switch?

I've fixed it! It was the inertia fuel cut off switch which was stuck on. I removed it with the plan in mind to bypass it then I chickened out on that idea and put it back on. The fiddling around with it must have switched it off . Everything works now, the relay's not buzzing any more. Brilliant!
