You are right Ed, bad gas is about the only thing that comes to mind anymore... but it would have to be really bad gas. It was mogas from a different (cheaper) gas station than usual, and it had been sitting for about 3 weeks while I installed my smoke system.
At one point during the exercize I did accidentally run the injector test mode with the fuel pump running... I figured I was pretty much done after that so that is when I removed (and exchanged) the spark plugs and spun the engine by hand quite a bit with the plugs out. Then put it all back together without any better luck.. I guess there still could have been too much fuel in the manifold even after spinning the engine.
So maybe a little bad gas caused the initial problem, which I tried to solve by running the injectors in test mode and made the situation hopeless. Will try again in a few days.
Thanks for all the help, I just had to vent a little.

Hi Dave,
Since you seemed to have checked everything else – how about the fuel quality – seems that is the only thing you changed since your last flight., Not certain what you meant by re-drained it– is it sure nuff 100LL or Autogas? Nothing perhaps diluting it?
But, other than too much fuel (flooding) sounds like you have all the essentials for a running engine.

Subject: [FlyRotary] WTF? Just when I think everything is going perfect...
Yesterday I went flying and tested out my new smoke system... everything was perfect... somke is fun. Today I head out to go formation flying.. nothing changed from my flight yesterday except for adding fuel. But it won't start... I verify that I have fuel pressure, fuel flow, injector function (in test mode), I have spark (in test mode). Maybe it is flooded... I change the plugs, re-verify spark in cranking mode (to eliminate issues with CAS), re-drain the fuel, verify compression, re-verify fuel pressure and flow and injector funcion... but still it just turns over without starting... Sigh
Anyone one know of a new component necessary other than fuel, spark, and compression?
