Volvo Fuel Pump Relay controller Up for sale is a volvo Fuel Pump controller relay. This is the primary cause of non non working fuel pump, or power cutting out to the fuel pump. This translates to a car that will stall randomly or one that won't start, or random stall outs. The pins on the relay can become burnt or the internal points or springs wear out. This unit was checked and tested and is functioning normally. Part number on this relay is 9434013 / 89 8770 000 . this is also a good part to keep as an extra, as it can go bad at any time! they are well over $100 at the dealer... Check your old unit to verify that you have the correct one, as there are several types. I have several listed which will fit almost all 240 740 760 940 780 850 and 960 V90 S90 V70 S70 etc... Thanks for looking
