Car turns over OK but wont fire - Recently changed battery. Oil warning on dash showing ----- which is flashing. Checked oil - bit low - so added a little oil - now shows oil OK but still wont start?

thanks to AA solution found - so I thought I would post.

Salt on road as got into the relays and board located in front of battery on the near side of car under the cover. All relays where removed and were awash with green copper oxide from corrosion which also was present n the relay board itself.

Following cleaning and copious amounts of WD40 it fires up and works fine.

Best news today though is MOT passed without issue!
