J001 Posted July 7 Report Share Posted July 7 I’ve got the following problem if anyone is able to help 2 relays wired negative trigger for the fuel pumps in the swirl pot. The relays are staying latched with the vehicle off, They’re both wired up with their own fused perm live from battery to pin 30 with a jump wire to pin 86 Pin 87 provides power to the fuel pumps Pin 85 is the only shared wire and is the negative trigger from the ECU (G4x Fury) The fuel pumps are earthed directly to the chassis As soon as I add the fuse into the perm live with the ignition off, the relays they turn on My guess is that the pumps are back feeding and holding the relay closed Is there a way I can stop this? Appreciate any help Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 7 Report Share Posted July 7 The coil supply (86) should be ignition switched +12V for a normal aux. If you have a spare ignition or injector outputs you could move your relay trigger to them as they are ok to have a live feed. Quote Link to comment Share on other sites More sharing options...
