2007 ISX fuel pump will not work after filter change
I serviced 2007 ISX including fuel filters and turned on key to start electric fuel pump to purge remaining air from secondary fuel filter the pump did not turn on as it usually does with this procedure . I removed filter & toped off with fuel reinstalled and started truck. truck ran for 30 seconds and died. The pump still wont run. I checked for voltage to pump. There was none . Checked fuses &relay found no problem. it is a 2007 KW T800 please help
Is this a good question?
