Tommotankngn Posted March 6, 2023 Report Share Posted March 6, 2023 Hey Guys, Have just installed a link plug and play to my R32 with Rb25det. When I turned the ignition on I could hear the relay in the boot clicking (fuel pump relay I believe) I checked all my earth's, removed ecu plug to check pin contact relised my injector loom wasn't plugged in aswell. Plugged in injector loom and when the ignition is off the injectors are clicking. I found a pin out of the ecu I had previously plugged in which was a RB25DET ecu and wire colors are different on the loom but it was running perfectly before fitting the link so surely wiring is okay? Anybody had this problem before? and should the link ECU blue light be on when ignition is off? Cheers!! Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 6, 2023 Report Share Posted March 6, 2023 What you are describing sounds like a back feed. The ecu is being powered up from 12V "leaking" through the fuel pump relay. Most likely someone has wired the fuel pump relay wrong, the 12V on the fuel pump relay coil should only be live when the ign switch is on, yours must have power all the time.
