that was your bad rocker arm, right?  Any chance something is still not right there and your exhaust valve isn't cycling in sequence?

well, I don't know why, but the brake light is coming on now like it should.  I flushed the MC a few times and re-ran the PM motor, so I think I have clean fluid in there.  I flushed only one brake line before the storms rolled in - rear passenger.  I still have a motor that won't shut off and weak brakes, so I ordered rebuild service from rock-auto. It was right at $230 with master cyclinder, but they only had one left at that price - it was marked wholesale closeout.  We'll see.

too late to help, but when you did your compression checks - did you remove just the plug for the cylinder you were working, or did you remove all 6?  I wonder if pulling all 6 for the check might have isolated this sooner.
I posted a different question, so I figured I'd better keep things even try to help someone.  So far, I can't.  But since my car has sat as long as yours, a little empathy for your problem is as close as I can get.

GN's been sitting for 4 years since I  moved to Indiana, and now I'm moving to Houston.  (I just realized I'm 10 minutes from PTE, oh well).  It started up fine and seems to run ok, but the powermaster won't shut off unless I unplug the motor, or unplug the grey brake switch.  Both shut the motor down.  The troubleshootin g guides I could find reference special GM tools.  My brake light is not on.  The pump pumps fluid out of the reservoir, and the levels seem to hold (or at least change slowly) when off.  The switch seems to always read ~2.4ohms across all 3 pins, any combination.  I would think if it were the switch, I'd get a brake light, so maybe its the motor.  Before I do that, the fluid looks like crap, so I will flush it out.  Any input?  I need the brakes to work well enough to stop the car when I load it on the truck.
On second thought, I'm going to check the brake light also.  That might explain why I don't line up with the troubleshootin g guides.
