Geeesh...the mouse froze again.
To continue, I got a moderate, steady stream of oil coming
from the remote filter mount. So, I had some flow. I then
went to the end of the hoses where it re-enters the engine
after flowing through the two oil coolers. Well, here there
was no joy. No oil coming out. I did refill the filter
before I reinstalled it and cranked the engine for quite a
while to no avail. Next, I unhooked a few of the other hose
connections past the filter and still no flow when cranking.
Finally, I checked all the way back to the filter outlet and
no oil would come out. I changed to a different filter and
still no flow from out of the filter. So, I have some
flow....not a lot into the filter buy none out.
I HATE the idea of dropping the pan (will be a real pain)
to check the oil pump and pressure gage, but I am not quite
sure as what else to check at this point. When I return
tomorrow, I will remove the plugs to take some of the stress
off the starter and see if I get flow out of the filter. I
am also concerned now that I have been cranking the system
long enough that some important parts are not running with a
lot of needed oil, such as the PSRU etc.
If I would have just happened to look at the OP gauge, I
would have never known there was a problem as the engine
"sounded" strong and smooth and continued to do so when I
started it to test my pressure after discovering the problems.
Hopefully this will be a bit more directly answered by the
engine guru types on the list since it is not specific to
Tracy's electronics.
Please, what else should I check, I am about at the end of
my testing skill set. Also, what say ye as to what the
problem "sounds" like????
Thanks, as always.

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
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
