Re: problems with FAV solenoid - no work, but getting very hot!
The strange part of this test is the ~12V signal on pin 1. It should not be there when the FAV is not plugged in. It is especially strange it changes between idle and loaded.
Can you rememer if there is any sudden change conincide with system problem. Other than the engine rework. Are any of the wires been disturbed.
The next step would probably be unplugging all the RJ connectors (including the gauge), just leaving the grey harness plugged in.
I would like to concentrate in the test point 1 with only grey harness plugged in. Then retest pin 1 as follows:
1. Just the molex
2. Just the pump harness (blue)
3. Just the FAV sensor harness (yellow)
4. Lastly the gauge.
I like to know where this strange 12V comes from. If the 12V is present before with only the grey harness plugged in, we have found the culprite.
