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

[RDM1]

No click or spark while cranking aswell

 

[koalar]

I was thinking is it possible because I'm probing directly on the back of the injectors and coils? Should i do it on the looms?

You can't see the pulse with my test light at all,

 

[RDM1]

How fast is it theoretically at 300rpm?

 

[RDM1]

But as i said previously the injectors are sealed shut and will open when i add the 12v tester or lamp on the ordering line you clearly hear the tick and smell the raw gasoline everywhere but on the scan tool there's nothing and while cranking definitely inaudible

 

[RDM1]

How fast is it theoretically at 300rpm?

I'm guessing once to twice per second so it should be visible with the led light i suppose

 

[koalar]

It's the duration its to brief

We are pretty sure the ECU isn't switching, it's almost like half the pins aren't touching, connectors are fully down and locked

 

[RDM1]

I know but let's calculate it if the car is cranking at 300rpm/60seconds you get 5 which means 5 rotations per seconds and compression explosion then emptying the chamber you cut it by 2 means 2.5 times a second so the led should go on then off 5 times every 2 seconds

 

[RDM1]

Unless fiat are using some sort of double combustion process

 

[koalar]

Duration is the problem

2.5 ms

 

[RDM1]

Shouldn't it be 250 ms?? Or so?

 

[RDM1]

Can i graph it on the scan tool?

 

[RDM1]

Duration is the problem

2.5 ms

Oh i got your point now as to how long it is energized for

 

[RDM1]

The ECU is freezing as soon as i crank probably a low battery will charge it tomorrow but hear the car's cranking voice is it normal or did something in the engine happen?

But you have your foot on the brake and gearbox in neutral while you crank it?
Something is prohibiting the ECU to give fuel and spark.

No point in cranking it in the last video

The dash says

Stop & turn the engine off

Temperature gauge is at max

Try pulling the cable from the temperature sender

 

[RDM1]

Probably because the battery is almost dead and it used to do it while driving when it was running back in the days at random any idea why this does happen?

 

[RDM1]

As you can see it happens for a few seconds then flat out afterwards

Yeah after mentioning that the foot on the brake pedal is necessary i did but it's the same i used to crank it from the window with only the neutral and used to fire up and sometimes my dad and sister used to crank the car without putting it in neutral or pushing the brakes the car would nudge a little (a little push off the starter with the gear engaged) then the car automatically shifts to natural and starts sounding the warning that the car is not in the neutral afterwards you just have to push the pedal shift to neutral then reengage the 1st gear while the car is running my car never actually cared for a pressed brake pedal but still the ECU is reading it properly i checked it on the scan tool

 

[RDM1]

And if you're about to say that this is not normal i can say it is because i had a woman with a dualogic 500 that behaves the exact same way as my car unless both cars are not normal

 

[RDM1]

So we officially gave up?
