_Matt_ 32 Posted October 2, 2020 Hi, Following on from other thread about check valves... my fuel pump is running constantly. Key doesn't have to be in the ignition - I don't remember this being a feature of the car! It has just come back from the bodyshop. I'm aware a constantly running pump coulld be a fried ECU but plan to check earths first. Any tips or past experiencs would be great to hear! Cheers Matt Quote Share this post Link to post Share on other sites
fendervg 33 Posted October 3, 2020 Sounds like something is bridging battery live to the fuel pump - I'd check your ECU and fuel pump relays under the driver's side dash - I think (from memory) that 109 is ECU and 167/67 is the fuel pump, but a quick search should be able to confirm.

fla 9 Posted October 3, 2020 As fender suggests, pull the 167 relay and see if it switched the pump off. If it does, best to replace it. As a short term fix you can pop the cover off and clean up the contacts assuming its got stuck between the poles. Then use 12v to see if it opens and closes cleanly before putting the cover back on.
