Subject: [FlyRotary] Houston, we have a
problem...
I plan to go back and read the list, espcially
the stuff on Buly's recent issues, HOWEVER,
I went out to the airport after work today to
show off my running engine to him. I flipped the switches UP <g>,
hit the start button and it started up. It ran for a bit fine, but since
I was afraid I may be running it too fast and don't want it to get too hot (if
you remember we do not have any sensors or the monitor hooked up yet, so we
have been VERY conservative since first start on Wednedsday) I throttled back
to slow down the engine. I must have throttled back too much and the
engine died. I have had this happen before, so I pushed the starter
button again and the engine just turned over and would not fire. Sounded
just like it did on Tuesday when we had the injector switches reversed
on/off...so, seemingly, no injectors. Nothing unusual happened...no pop,
no bang, no sparks, nothing.
My ECU does not have the trouble shooting upgrade
yet, so I checked the plugs while turning over the engin with fuel pumps
off (no prob on as of yet) and I have spark. However, we do not seem to
have any noise coming from the injectors at all. I tried on both A and B
to no avail. After checking to see if any wires had come loose and
other basic trouble shooting, I was becoming frustrated (and a little
angry) and for the first time in my 4.9 year build I was
feeling a bit discouraged.
I am new to fuel injection and ECU's. Any
quick guidance y'all may be able to provide on where to start will be
appreaciated. I did check to see if the injectors were getting any power
by using a test light where the wire goes into the injector housing and three
seem to be getting power on both wires (both primaries and one
secondary)....every once and a while during this "test", I would hear a slight
click, but that was inconsistant. When I checked for power at the
resistors (as our set up uses them), the primaries did show power but the
secondaries did not.
This has probably all been coverd on the list and
I will try to find it, however, I am about to hit the sack since I get up at
4:30 am for work and 10:15 pm is well past my bedtime <g> I did
take off tomorrow and I hope to spend most of the day in the hangar, so any
quick insight that I can apply tomorrow is greatly appreciated. Heck,
just y'all allowing me to vent for a few minutes is reelly helpful.
Thanks.
All the best,
Chris
