Don,
I suffered for a long time with the same symptoms and found my vacuum line was leaking. Disconnect the vacuum line from the intake manifold and apply some vacuum by mouth. (it is nice if you can see the MP numbers on the EM2 at the same time. Use an extension hose if you have to). See if the values are changing. Pull some vacuum and pinch the hose. If the numbers go back to atmospheric, you have a leak. But again, it could be a different gremlin? :)
Please keep the prop area clear while on testing the plugs mode. The engine will fire and it could hurt someone.

The list has been a little quiet lately, so I hope this will liven it up a little.  I'm at a loss as to how to get my engine running, so hopefully you guys will have the correct answer. Or at least move me in the right direction.
    My renesis RV-8 is complete and I tried starting it 2 weeks ago and all I could get it to do is flood.  First a little background on the installation.
    New Renesis, 4 port automatic from Bruce Turrentine.  He does nice work!  All Tracy's stuff with all the new upgrades and I have installed a floscan fuel flow sensor with the wiring changes between the EM-2 and EC-2.  Also have Bob's wiring harnesses to the EM-2 and EC-2 and the LS-1 coils.  I have installed the primary/secondary injector disable switches and the coil disable. Bob's  harnesses are the way to go!  I have gone through and checked all the wiring with an ohm meter.  Even pulled the crank angle sensor, unpotted it and brought it home where the repair dvd is and it reads the correct 1193 ohms and there is a change when I move metal near it.  The crank pickup wheel can only be mounted one way so than can't be the problem.  I have set everything back to the original settings on the EM-2.  I have run the new injector test (Mode 2) and they click like mad and I can turn them on and off with the Inj disable switches.  I have pulled the irridium plugs and tested them (mode8) and they fire a bright blue.  Tracy, love the test modes!  I have tried all of the ways Tracy says to start it and all the ways everyone else on the list does it.  Still floods. I am getting very tired of taking the plugs out, cleaning with carb cleaner and blowing them out and then cranking the engine to purge the fuel.  My neighbors are very good to stand by with extingishers and telling me to stop when gas dribles out the exhaust.
    I have checked my fuel pressure with a seperate gauge, 34 psi one pump, 37 with 2.  Using O2 sensor, but of course that does'nt kick in until auto-tune.  I have the stock red Renesis injectors in the primary ports and the blue in the secondary.  These injectors are used, but I had them cleaned and flow checked.  Yes I know that the rear rotor, next to the pully is rotor 1 and of course the leading and trailing plug hole are marked as are the spark plugs.  I have triple checked that the manifold lines are run and attached from the intake manifold to the EC-2 ports and the one on the EM-2 is left open, as per the manual.   Tracy says that he has set up the EC-2 for the stock Renesis setup. Yes and I try both A and B controlers.  No change.
    The only time I could get the engine to pop, was when it was still partly flooded and I hit mode 8 to fire the plugs. One pop.  This is being done with a fully charged, new Oddyssy battery.   So, I am getting spark, fuel (lots) and air.  No way to check the timing.  After 2 weeks of this, I am at a loss and could use your suggestions.
