Non starter

Hi people. My 850 T5 has been stood for a while, on jump starting it this am it fired up fine. It ran for 30 seconds then cut out. Now when I get the key to the ignition position the usual hum (fuel pump?) sound is missing and when cranked it just turns and wont fire. I cant even think of any way to search the forums as I am at a loss. Any ideas ?

If it is the relay and you are handy with a soldering iron, fix it yourself. It's the two upright caps on the board needing relpaced.

Thanks guys, the fuel pump relay was the culprit. WD40 sorted it must have gotten damp sat as it was. Now happy bunny. Cheers.
