Thanks guys. I am about to go out to the
hangar and try some more. The fuel pumps are working but I will have to
check to make sure fuel is not locked downstream. I checked for spark and
it was good, also, with the upgraded ECU, I have checked for injectors and I can
hear them clicking (even though I am concerened that I heard the injectors
fireing as if in mode 1's test mode while in mode 0 a couple of times
when I hit the program button to prime)
Ed, thanks, I have a prop (an IVO inflight
adjustable job). I have been very mindful of not letting the engine get
much past idle. The eratic readings on the EM seem to be just on the EM
and not reflecting what the engine is doing. The readings will flash to
the higher readings for an instant, then change to some other eratic number even
though the engine is running at a consistant setting.
I still would prefer to check for leaks without the
prop, but as you say (and is in the manual) little more can be accomplished
without the prop. The prop kinda makes it a bit scarier
<g>
I willl keep ya posted. THANKS
again.
Chris

Chris,
Do you have fuel pressure? Can you tell if the fuel pump(s) are
pumping fuel? If you ran them dry, and don't have the bleeder circuit in
the fuel rail, then you may have an air lock downstream of the pumps. If
that's the case, crack open a fitting downstream of the fuel pump(s)
and run the pump(s) until they re-prime. You should only
need to run the pump for a few seconds before it re-primes. This is why
I installed a bleeder circuit on my system. This would be very bad
if it happened while flying. The bleeder circuit does the same thing as
cracking a fitting to let the trapped air escape.
If you have fuel pressure (pumps primed), then I would check the
fuses/cb's to the coils and injectors. Then I would pull a leading plug
and look at it to see if it is wet (getting fuel). It may be flooded
(not likely though). If you have upgraded your EC-2, you can run the
injector and coil checks to see if they are working.
Good luck,
Mark S.

I got the EM working on Sunday after work. As I
said, I ran out of time in the hangar the other day, so when I was able to
get back out there after work yesterday, I was able to hook the dimmer knob
to the EM. Turned it up and I got a visual on the instrument. Whew.
I am having VERY inconsistant readings for RPM. it will "bounce"
from the 3000 rpm range to 8000, then 6000 ish, then back down to 3000.
Mostly in the 3000 ish range, but still VERY eratic. Don't know what is
causing this yet. Maybe due to no load? (as was stated somewhere, I prefer
to look for leaks and finish running wires (now that basic wire run routing
seem to be ok) withOUT a prop turning next to my ear....and neck at 3000
rpm. Also, it seems to start great one time and then not really want to
start at all the next time I try. Geeesh.
Well to follow up, today
was one of those good bad days....or bad good days. I feel like I got stuff
done, but in the end it was unsatisfying.
When I first got to the
hangar, I kinda went "what the hell" and decided to start the engine. I
pushed in all the C/B, all switches up (except for the "A" ECU switch and
the cold start switch), primary pump on, mixture knob rich, hit the start
button and immediate start. Loud as hell, but it was running. Kewl. Only let
it run for a very short time as I didn't want it to get too hot to work on.
The RPM' readings on the EM were still very eradic, but other sensors that I
have now connected (oil temp, oil pressure, water temp, water pressure) at
least were reading SOMETHING.....thats a start.
I went about the day
making things a bit more secure in the engine area running a few more sensor
wires a bit more properly, chasing down and hopefully securing a couple of
known leaks etc and, DAMN IT, before I knew what happened, most of the
day was gone and Jana was telling me it was getting late and we needed to go
home to eat (she had been watching TV patiently.....uh, this time , on the big screen we have in the hangar ever since she had
arrived with our dogs after she got off work earlier in the afternoon). "Oh,
OK, let me finish up a couple of things (always) and then let me start it
again before we go........here baby put on these ear gaurds". Yep, it
started, did not run great, but it ran, then it seem to run out of gas and
stalled. Hmmm, I think I really ran out of gas (I only had a few gallons in
the sump tank). So, we put more gas in, but for the life of me I could not
get it to start again........seemed to want to start a couple of times, but
a few times it didn't seem as if it had ever started . Jana left to go start dinner......I stayed for more of the
same . Gee, another hour past already, geeezsh, I gotta go, it is
getting dark
.
Oh well, at least I get two days off a week, so back
again in the morning and see what I can do to get it running again and
maybe, hopefully to consistantly start. <sigh>
Thoughts and
comments are welcome.
All the best,
Chris
