In order to prevent damage of gate pad it is advisable to not direct heat it with soldering iron tip .Just put the wire near the pad ,heat it with iron ,apply solder to wire and let it drop to pad .
If transistor fail again ,dont unsolder gate wire from the pad ,just leave it there and reuse it.
Found some videos on YT about VP44 ,most of them in russian .I ve noticed they use to unscrew a T30 port near the exit pipes to measure internal pump pressure (from 8 bars at idle to 30 at 4000 rpm ) ,which would be a good indicator of mechanical state of the pump.

Does anyone know a test which can show mechanical condition of the pump ,before trying to repair electronic module ?I have too many failed attempts ,car don t start or car broke again soon ....Or which are the symptoms
for mechanical problems that will cause fail of electronics?Until now it seems that most successful are when the car stop suddenly ,with no signs but when when car become sluggish then stop it is mechanic cause so repairing electronics is a waste of time and effort..
I have an opel VP44 on the bench now,if I turn it clockwise with a driller it will activate the valves,this does not happens with the Ford one ,so I am looking for method of make immoff or virgin for Ford module .
This could be useful for testing a pump on the bench ,rev it with drill and measure pressure at T30 output.
