Just after some advice please. Been out of the seen for quite some time, just started getting back into reviving my old RST. For some reason, before firing the engine up, normally the fuel pump primes, you hear that loud buzzing noise. For what ever reason its not working, no priming. Therefore, no fuel, she wont start. She is on standard MFi fuel management.
I haven't yet picked up a spanner, just wanted to pick your brains first and see if any of you had this problem, and what you did to resolve it.

Any advice would be greatly appreciated.
