Thanks, I will when the parts get here. Mainly because I have some corrections I need to speak about. But the parts was ordered and should be here soon.
The brown/yellow injector wire that you mention goes down the rail to a pin on an Ignition capacitor thats mounted on the rear of that same side engine head where the coolant tube mounts to. This means this car has a CID starting system. That little capacitor is probably faulty allowing stored power to run to that circuit through the capacitor when everything is shut down. Its a rediculous $20 part from any dealer. Or the alternator duty cycle wire, the pcm wire from C2 pin 19, the EGR sensor ground and others that are all spliced together at splice location S115 then run in the same circuit Z904, that come out at that capacitor at location, there could ve a short to power somewhere G105 in the repair manual. or bad alternator diodes... I swear, i try to exhause every possibility other that replacing that dang PCM. LOLOL
Hi, I'm from Australia and I'm also a mechanic and I enjoy your work and thought processing. Question: what is that test light called? I assume it has two clips for positive and negative? Thanks, and say hi to cousin Pookie for me
The asd is staying energized when it shouldn't. And the #1 driver in the ecu is always hot. Two problems originating from the ecu. But how does a coil blow apart?
With switch on shouldn't the ASD relay be energized. But diagnosis is correct with bad pcm because the coil should have a duty cycle or pulse width modulating which interupts the circuit which in turn causes the secondary windings in coil to fire off. So if signal wire or pcm control wire is grounded at all times means circuit is dead not allowing an interuption in the circuit.
ASD on for maybe 3 seconds when you turn key on (prime fuel pump). If the pcm don't see RPM from enine crank sensor, back off it goes. No sense powering those injectors or coil if the engine not running.
Great video JT do a part 2 👊🏻

@ you do these types of learning videos you will be hitting higher subscribers numbers
Eric O had this similar problem on a Chrysler 8 years ago it was frying the coils 👊🏻 ASD was activated open by CM sensor

Very informative video, thanks.
Hopefully the car owner approves repairs so we can watch that video.

Interesting!

Heat
Yep, it over heated and popped from being constantly on so it never cooled down between firing the plug.

@@OnlineMechanicTips 10-4, i forgot about the 3 second prime. Love the video's good for the brain!
@joesmo4749 Thanks for tuning in Joe.
