The
way the fuel rail is set up it is certainly part of the fuel flow return (I have
posted pictures on www.canardaviation.com of the fuel rail
for the Mistral). I agree that I can't imagine that it would prevent
start.
We are
not sure if my EC2 has the troubleshooting mods or not. We should get
more insight when we can play with it a bit more. Sure hope so....but my
unit has been sitting on the shelf for a while. I can;'t remember when I
actually got it. We did send it back for the "choke" circuit
replacment. Donno if anything else was modified on this tri back to
FL.
Of
course Murphy is playing his role in that after having my ECU, EM and PSRU for a
while, this is the first time I have needed to have Tracy around.
DOH! Actually, hopefully we are not to this stage yet, however, since all
the sensors included with the ECU/EM have been misplaced, it would have been
nice to be able to order more. My timing can suck
<g>.
All
the best,

Chris,
A pin hole at that point might be meant to let any vapor
escape and route back to the return line rather than the main fuel
return. A pin hole will certainly not flow back very much liquid
fuel. At idle most of the fuel would normally be returned, at WOT much
less of the fuel will be returned. However, this should not stopped the
engine from firing.

Well... Not Quite..
I
was wondering about the fuel return too, not as to why we are not getting a
start, but more in general since the Mistral intake has a pin hole at the
end of the fuel rail as it enters the return hose.
The return line is the same size as the inlet lines.....fitted for a
AN 6 connection (can't think what makes the hose)

Have you tried the injector simulation test to see if the injectors
are working?
How
long has this feature been in the EC-2? I was thinking this was
a new addition, so most people still wouldn't have it??? I've sure
never known about it until recently, and I made a note to try mine to see
if this works.
I would
vote for fuel as well, though I'd also recheck the CAS as Ed
mentioned. If you did that much cranking, some with cold
start on, you'd have to smell fuel in the exhaust if your injectors were
working.
As for
fuel pressure, what size is your fuel return line to the tanks? Most
people get a couple psi increase with the second pump. To get as
much as you have, I'm thinking the fuel return can't flow enough to return
the volume from both pumps at once. This isn't necessarily something
that has to be fixed though.
Good
luck,
Rusty
