How many volt is there? I think i can manage a bulb to test with it I don't think I have 6v but 3 there is and 12 too

Ok and tried with the multimeter i got 0.135v and 0.55v while cranking between negative and the yellow/brown wire on both plugs the higher value is for the rear coil plug

Values are not accurate there's no power at all on them even tried on the DC too

So ECU is cutting power to the coils what might be the reason?
Right back in the house
It has to be a LED a bulb will short circuit the coil and stop it firing anyway
Not the results I was expecting
0.135v and 0.55v was expecting no change while cranking
Have to have a think where to go next

Welcome back but what do you mean with what you said here?

Because if you mean putting on a 3v bulb i doubt it'll light at all even with the initial 1.2v initial spike

Anyway my question is can a faulty bcm cause the ECU to cut the signal?
What is the resistance between the two pins on the coil

I don't know I'll go check that but my question is: is the tester the guy in the video using a 12v tester?
Yes 12v led test lamp
It's just too quick for the multimeter to measure
What is the voltage at ignition on for the 2 seconds

On the ECU signal it's almost null or something about 4mv it's always like that even after the 2 seconds at first but when cranking it goes up

But now thinking about it when the car decides to fire it runs normally and no spark on all 4 spark plugs with the other wire giving a normal voltage on the other wire (coil plugs) means that the ECU is cutting the signal himself

Now as i previously mentioned i suspect the BCM to be acting up because last time the car ran after i cleared the BCM faults while it was running, the engine immediately went out

What the resistance across the coil pin
Both coils
Both coils
Does it measure quickly or fluctuate

So this is a 12v lamp i had and each video is for a coil
positive battery terminal and the ECU signal wires

I'm getting also an absolute 0 ohms on both coils
If the immobilizer is off
And you have a crank signal
You should be able to hear the injectors firing
