I have a 91 Fiesta RS Turbo drove it about 7 miles, stopped and went to start it again and now it wont fire up. At first it wanted to but now...nothing.

Checked the fuel pump relay doesn't seem to be burnt out and the wiring seems to be fine , also seems to be earthed correct. I haven't tested to see if there is power to the pump. to be honest i'm unsure how to..

Is it worth changing over the fuel pump relay? if so where can i get one?!

Just to confirm is it the middle yellow relay?

Cheers in advance
