Now and again it just cuts out, bought a new fuel pump but that dint work,
what happens is you can here something short out sounds like a buzzing coming from fuse board for a few secs rev needle throws a fit then cuts out, but then leave it for a min and it fires back up.
Does this sound like a dodgy fuel relay, is this common for s1.

 

proberly fuel pump relay

 

could try the fuel pressure regulator......mine kept cutting out.

no probs starting afterwards.

 

If the rev counter is having a fit you will probably find its the dizzy breaking down, the series 1 fuel relays take a signal off the dizzy, so that would explain the relay clicking and the rev counter going tits

 

thanks people will let you know the correct answer soon
