Red voltmeter probe to B+, and black probe to the relay 86 terminal shows 0V. Sounds good.Testing 86, Red prone to Positive on battery and to 86 shows 0
So with the red voltmeter probe to B+, and black probe to the relay 85 terminal you get 13V.kici said:and then tested to the 4th wire main relay ctrl wire shows 13 V
Meaning the ECU is pulling the relay ctrl terminal to ground. That sounds good too.
Is this the terminal you said had 9~10V in your original test?
The fuel pump wont work if the MAIN relay isn't switching on. The MAIN relay supplies power to the F/PUMP relay.kici said:On the fuel pump (back seat is put up) I tested the black and red to see if anything goes to it when I turn the key - nothing, and i do not hear it.
