Guest |471| Posted March 26, 2011 Report Share Posted March 26, 2011 Running a V44 plug in board and would like to drain the tank, how do I activate the fuel pump ? Quote Link to comment Share on other sites More sharing options...
Guest Dave-Kriedeman Posted March 26, 2011 Report Share Posted March 26, 2011 Easiest way is to remove the fuel pump relay and bridge the battery positive feed wire to the fuel pump supply wire. On a normal relay you would be bridging the pins that are relative to pin 30 and 87. What vehicle do you have. Quote Link to comment Share on other sites More sharing options...
Guest |471| Posted March 26, 2011 Report Share Posted March 26, 2011 Hey Dave, yes could do this but tuner that did my car said he turned on pumps via Vipec ? Car is an Evo 9 with surge tank and 044 external pump switched via in tank pump relay so easier to do both pumps via ECU. Quote Link to comment Share on other sites More sharing options...
Guest Dave-Kriedeman Posted March 26, 2011 Report Share Posted March 26, 2011 Go to AUX Output that is controlling your Fuel Pumps. Click on the drop down arrow and change your selection from FUEL PUMP to TEST (ON). Dont forget to change back to FUEL PUMP when finished. Sorry about my previous reply, i normally do it that way as it saves having to hook up the laptop etc. Quote Link to comment Share on other sites More sharing options...
