Replaced the coil pack, plugs and the ASD fuse. She lives again. Thank you all for your suggestions and help.

Where are those diagrams from? Those don't look like the typesetting found in the FSM.

They’re not from the FSM, they are from the TechAuthority PCM training documentation.

@Painfultruth would you kindly elaborate on the functionality of that transistor?
Would greatly appreciate it.

Is that a transistor? It only has 2 legs wired up.

 

[Painfultruth]

The transistor is the on/off switch for the ASD relay, it applies the ground so the relay can activate.

The transistor control signal (the one not shown connected) is supplied internally when the ignition is turned on. The control signal will remain active until the timer expires or the input from the ASD relay is removed (ignition switch off).

@Painfultruth Thank-you very much!
