Buly,
I have the opposite problem. When hot,, mine start
somewhat hard. Especially if it has sat for a while
and has a good heat soak. I believe that my intake
gets hot, and is what causes my hard start when hot.
On your problem, I used to have an issue with cold
start, before I added a cutoff switch for the primary
FI pump. I had trouble leaving pressure on the fuel
rail, because it seeped through the injectors and ran
out of the throttle body. Some ran into the engine
also, which caused it to be flooded. Wet plugs are
hard to get started.
On shut down, I turn off the primary FI pump, and let
the engine die before cutting off the master switch.
No more problem with the flooding. Also, if I do
flood it (hot start), I shut off the fuel pumps, and
when the engine fires up, I flip the pump on and the
engine continues running.
FWIW,
Steve Brooks
If your problem is flooding, I can see why priming
doesn't help.

Today I did couple of fast taxis with my test pilot
that flew the plane the first time with the turbo and fixed pitch
prop.
We had 500 pounds on the front seat and the plane
lifted off the runway in less then 1500 ft. He said it is a great
improvement from V. 1.0. That's the good part. Last few times I had
trouble starting cold. If I give it a sniff of the starting fluid it
will sputter and I have to turn on the Cold Start for a second or two
to get it going. Before start I hit the primer 4-6 times, but it does
not help. After it worms up, starts instantly. Anybody with ideas to
improve the situation? Thanks.
