1.9Tdi engine kicking

[hamma]

Hi, am here again with some new updates.
well, to start, my problems are the more and more bigger. the kicks took the place of the normal run and the normal run has become rare until yesterday the engine started shutting down because of a kick at idle run and than a total stop on the highway!

i decided to do whatever is necessery to get it starting again.
with a voltmeter, i measured the voltage at the fuel shut-off valve and i found a very weak feed (4V at best) and some times it goes to 7V and then goes down again to 4,3,2V and even 0V. so i took a wire and i brought the +12V stright to the valve an important spark has been thrown and the car wouldn't start again. i fixed the +12V wire on the valve after removing its original wire and than the car started again, but with a poor engine performance. the engine is getting hot quickly

So the question is: have i damaged my caculator? have i damaged my engine? what could this power loss come from?

Hi there!!
I have great updates!! problem resolved )))))))

i ll be short, the problem was a short-circuit at the fuel shut off valve with the fuel injection timing +12V wire and the ground.
result: sporadic power loss at the fuel valve --> engine goes off and goes back on quicly which explains the kicks
the +12V wire (3rd one on the connector) of the injection timing solenoid is the same as the nbr 3 wire of the MAF sensor, the N75, the EGR solenoid, the brake pedal and the cluch pedal switches. this wire (red/white) is directly connected to the engine control unit. i was afraid that this short circuit had caused a damage to the ECU and hopefully, it didn't! there was a fuse (15A) at the ECM compartment under the carpet!

now everything is OK, i only need a new MAF sensor cause mine is completely dead

Hope this helps someone.
have a nice day
