Aggg. I need a new computer.  The mouse froze and the message sent prematurly.
 
Anyway, I rechecked the wires to the EM2 and at the sensor again and all checked fine.  Again, I started the engine, but was shut down as soon as I still saw no pressure.
 
Next, I hooked up two separate mechanical pressure gages in three different locations in the oil system, started the engine three times very briefly.  Each time the engin started and seemed to run fine for the VERY short time I allowed it to run.  No pressure reading on two of the test points, and about 6psi on the reading from the turbor engine outlet to the turbo.
 
Ok, I unscrewed the oil filter, which is located remotely just as the oil comes out of the front (by the pully's oposite the prop) of the engine.  I hooked up a remote start switch, climbed under the engine and cranked the engie.....I got a moderate, steady flow of oil

Subject: [FlyRotary] Oil Pressure Loss

In the never ending tradition of two step forward and three steps back, I was working on my RPM drop out at 6000 rmp (messed with seveal resistors to no avail).  As I was sitting on the ramp at idle for a few minutes, focusing on the RPM's I glanced over at the Oil Pressure and noted it was flashing as an alert and was showing almost NO oil pressure (4 or 5 psi).  I instantly shut down the engine. 
 
The engine appeared to be running fine before I shut it down.  I checked the wire to the back of the engine monitor and all was fine.  I also checked the continutiy of the wire to the sensor and it was good.  I started the engine again and it started fine and seem to run fine, however, the OP did not kick in so I shut it down again
