Chris,
First... Don't get discouraged. When you start feeling down, just think of poor Buly and you'll be feeling good in no time. ;-)
If I had experienced what you did, the first thing I would check is to see if you inadvertently hit a switch with your knee. Check to see that all the switches are in the run orientation. If that is correct, then I would check the plugs for fouling or flooding. If they weren't gas fouled, I would check that you had spark (you did that, but did you check the fuses to the coils?)
Then I would look to see if it was getting fuel. A quick test might be to give it a shot of WD-40 or a squirt of fuel into the TB and see if you get a brief run or pops from the engine. This would confirm that you have a fuel problem.
Also, be looking for a wire that may have gotten disconnected, maybe you caught it with your foot or something like that.
I'm sure ED, Lynn and others will have a bunch more things to check, but this is where I would start looking.

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
