Technical '06 Panda crank sensor issue.....

[RDM1]

I couldn't hear a tick when activating them but i hear fuel flowing in the rail

 

[RDM1]

It might be the fuel pump I'm not sure

 

[RDM1]

Can i plug a 12v led lamp and check in the injector plugs?

 

[RDM1]

I think it's a more sure way if it works as in if the injectors work being fed by 12v

It might be the fuel pump I'm not sure

Yes the fuel pump has to activate as well as it uses the same relay

Pulling its fuse should make listening for the injector easier

 

[RDM1]

What about the lamp tryout?

 

[RDM1]

Checked again on all 4 and yes there is only the ECU tick nothing on the injectors

 

[koalar]

What about the lamp tryout?

With your lamp

I don't know

I know you can't measure the signal with a multimeter I have tried

I now you can't measure the signal with a inconcesent test light, as it detects a fault and shuts it off

You can measure the supply side with a multimeter

Again it will have to be within the 2 seconds

 

[RDM1]

Will it work with the plug removed? Or am i gonna have to prob it from behind?

 

[RDM1]

But now is it possible for the bcm to cut off the injectors and coils?

 

[koalar]

The power side can be tested both way

It's better to back probe as it loads the circuit

 

[koalar]

But now is it possible for the bcm to cut off the injectors and coils?

Not if you can hear the ECU click

 

[RDM1]

Yea whenever i actuate a coil or an injector i hear the ECU tick. What might be the cause of that if the components aren't activating but the ECU is?

Assuming the scan tool is working correctly

ECU driver, short a component or wiring

You could try disconnecting both coils and trying the injector test again incase there is a short in one of the coil primaries

 

[RDM1]

The stable 12v is available

 

[RDM1]

Tried by unplugging them both and still only ECU tick when triggering the injectors

[RDM1]

Is it possible that the ECU relays (the one that is being triggered that are ticking) are not properly engaging? Or is there something else that causes this?

 

[RDM1]

And forgot to mention that the ecu faults i sent earlier showed up after the first clear but the second time they did not

 

[RDM1]

I have a possible try attempt (not sure if it works):
I unplug all the bcm plugs front and rear and then try triggering the coils and injectors after leaving only the big red main power supply

IIRC Koalar asked for the sparkplug put into the jaw of a jumpercable with the other end on the negative of the battery. What I read is you put the earth of the plug on the engine. To me that is not the same.
Rushing of fuel in the line is not the same as clicking injectors (easy to hear).
Wiring of the cranksensor is (AFAIK) still shoddy.

Looks like we are running in circles.
Kudos to Koalar's patience!
