Do you have fuel pressure? When you = first announced=20 your engine start, you indicated that you poured (2?) gallons of premix = in the=20 sump. Have you added any?

Subject: [FlyRotary] Houston, = we have a=20 problem...

I plan to go back and read the list, = espcially=20 the stuff on Buly's recent issues, HOWEVER,

I went out to the airport after work = today to=20 show off my running engine to him. I flipped the switches UP = <g>,=20 hit the start button and it started up. It ran for a bit fine, = but since=20 I was afraid I may be running it too fast and don't want it to get too = hot (if=20 you remember we do not have any sensors or the monitor hooked up yet, = so we=20 have been VERY conservative since first start on Wednedsday) I = throttled back=20 to slow down the engine. I must have throttled back too much and = the=20 engine died. I have had this happen before, so I pushed the = starter=20 button again and the engine just turned over and would not fire. = Sounded=20 just like it did on Tuesday when we had the injector switches reversed = on/off...so, seemingly, no injectors. Nothing unusual = happened...no pop,=20 no bang, no sparks, nothing.

My ECU does not have the trouble = shooting upgrade=20 yet, so I checked the plugs while turning over the engin with = fuel pumps=20 off (no prob on as of yet) and I have spark. However, we do not = seem to=20 have any noise coming from the injectors at all. I tried on both = A and B=20 to no avail. After checking to see if any wires had come = loose and=20 other basic trouble shooting, I was becoming frustrated (and a little=20 angry) and for the first time in my 4.9 year build I = was=20 feeling a bit discouraged.

I am new to fuel injection and = ECU's. Any=20 quick guidance y'all may be able to provide on where to start will be=20 appreaciated. I did check to see if the injectors were getting = any power=20 by using a test light where the wire goes into the injector housing = and three=20 seem to be getting power on both wires (both primaries and one=20 secondary)....every once and a while during this "test", I would hear = a slight=20 click, but that was inconsistant. When I checked for power at = the=20 resistors (as our set up uses them), the primaries did show power but = the=20 secondaries did not.

This has probably all been coverd on = the list and=20 I will try to find it, however, I am about to hit the sack since I get = up at=20 4:30 am for work and 10:15 pm is well past my bedtime <g> = I did=20 take off tomorrow and I hope to spend most of the day in the hangar, = so any=20 quick insight that I can apply tomorrow is greatly appreciated. = Heck,=20 just y'all allowing me to vent for a few minutes is reelly = helpful. =20 Thanks.

All the best,

Chris
