But I will check again, because after recent service which included whole rebuild of cylinder block anything can be changed...

You need to change the transistor first. It should not cost more than $1.00 a piece.

Good. This leaves out one possible problem.

I did not connect it to the solenoid before my tests - and it immediately showed 13.0V on the harness... seems like transistor was blown immediately after I start the system. p.s. and you won't believe, but they sell such transistors here in Russia for $3.00 (while purchase from manufacturer at $0.75 - I know the real price)!

Next step...
Can you check the voltage of the controller ground (bottom left of the test points), against chassis ground.

sure, will do it later today once I'm back home.
should I measure impedance between ground and accumulator (-) chassis as well?

Just to measure the controller ground against chassis ground. This is to check the system wiring.
Chassis ground is any exposed metal on the car body. What is the accumulator?

the voltage on 'ground' reference point is 0.00V when off and 0.01V when switched on.
the impedance is 0.0 Ohm when off. sorry for using wrong term: by (-) accumulator I mentioned (-) on car's battery which is linked to chassis on my car. what are next steps? I see lots of diagnostic points on the mainboard - should I check them? also I have checked again the information from fuel injectors (I have direct injection car) - it is correct and there are no problems here. the same about information from flow sensor and trunk harness...

This is good, no wiring problem there.
Please check the voltage of the following test points (against controller ground): (with the ignition on, engine not running) 1. test point 5 injector(+) 2. test point 8 injector(-) 3. test point 23 injector(+12) 4. test point 1 FAV drive (check resistance. not voltage) 5. test point 16 (IDC%) 6. test point 15 internal 5V reference 1 7. test point 11 internal reference 2 8. test point 30 internal reference 3 That is all for the time being. I would also like to have a good picture (well focused) of the controller circuit board (top side and bottom side). Like to see the settings and configurations.

Is it okay if I will test all reference points without FAV solenoid connected?
Since it is always under voltage it is getting hot which is not good, I assume - ok? Also, what to you mean by 'test point 15 internal 5V reference 1' - what is reference 1? Should I check all voltages and impedance (resistance) vs. 'ground' control point on the mainboard?
