Pin 6 of the power module is the pump drive signal output to the Control Fuel pump from the push/pull pair of power driver transistors.   

 

You must have been asking about some other pin or connector – you won’t get far without pin 6!.

Subject: Question, of course!

 

The lead from pin 6 of the Power Module to the CCC and ASDM.  Obviously

controls shutdown.  For what reason?  The ignition pulse train does the

same thing.  Can I disconnect it at the PM and ground the side to the CCC

and ASDM without losing anything?  Just trying to simplify this design.

Did anyone ever do a theory of operation on the Power Module?
