tim olsson Posted March 2, 2014 Report Share Posted March 2, 2014 Hello. Im running a rb25det in my s13, I have bolt in the link ecu to the loom and tried to start the engine. But I can't get a signal to the fuel pump. When I check in the link program the fuel pump is on, but I can't hear the pump running. What's the problem? Something I missed? Please help me.

Simon Posted March 3, 2014 Report Share Posted March 3, 2014 Do you have the G3 LEM with an adapter to the RB loom or is it a Linkplus to RB adapter or is it an LEM to S13 adapter? The ECU provides the ground to the pump control you will need to check; adapter matches application, main relay is powering up. fuel pump is getting signal, fuel pump isn't dead.

Simon Posted March 4, 2014 Report Share Posted March 4, 2014 We would be expecting the main fuel pump to be controlled through pin 18 on the factory header. Quote Link to comment Share on other sites More sharing options...
