wld4x4 Posted February 10, 2004 Report Share Posted February 10, 2004 I have been posting about my fuel pump not running when it is cold until the car builds oil pressure when cranking. After checking the fuse and trying two new relays I still have the problem. Does anyone know why the system relys on the oil pressure switch in the first place? And why can't I run a wire from the switch directly to the pump? I do know that the pump works when it gets a power supply. Link to comment Share on other sites More sharing options...
