well i tested it yesterday and im only getting 6 volts at the white wire. but also what i noticed is that the fuel pump wasnt working either. when i took out the fuse for ecu circuit everything turned on again. could it be maybe the main relay contact for that circuit is bad. and also what i was thinking was rerouting the circuit and putting in a 30 amp fuse next to the ecu.

main relay might be bad, or intermittant, its happened before
