Sam280Z Posted October 23, 2003 Share Posted October 23, 2003 Does anyone know what the small metal box in the upper right hand corner of this pic is? I pulled one with my harness, but do not know what purpose it serves. It has a JECS sticker that reads: 17001 P9000 A63-00 030. Quote Link to comment Share on other sites More sharing options...
Warren Posted October 23, 2003 Share Posted October 23, 2003 That would be the Fuel Pump Control Modulator, used on Turbo cars from 9/81 to end of S130 Series Click for fiche view Hope it helps. Warren Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted October 23, 2003 Share Posted October 23, 2003 Correct, fuel pump modulator. You don't need it. Quote Link to comment Share on other sites More sharing options...

Sam280Z Posted October 23, 2003 Author Share Posted October 23, 2003 What do it do? I assume it modluates the fuel pump but why does the fuel pump need modulating? Sam Quote Link to comment Share on other sites More sharing options...

Sam At less than full throttle conditions, it reduces the voltage to the fuel pump to make it quieter. Quote Link to comment Share on other sites More sharing options...
