Dead driver on '165?

[Mike Rolica]

It don't care.  The signal can be pretty dirty!  I grounded the wire
manually repeatedly until it started.  Kind of crude but it worked until I
got my vats killer going.
Here is what I know.  If ECM see vats during cranking, injectors fire, car
runs and it no longer needs vats.

cycle.
	This has been mentioned before, but I forget if here or DIY
