can't get it to fire up * it started before* SOLVED!

So...I can't get my vw 16v turbo to start. Running ms2 Extra with distributor/direct coil control. I had upgraded from a 1.8L to 2.0L motor. Everything else the same. It has started up (after several 10 or so tries) in the past with the 2.0L with the old tune. I haven't touched the project for a good eight months...
Now it's cranking...but not firing up. I had the battery tested and it is good. I checked the INJ1 And INJ2 power and it's reading voltage on the dvm. Also checked the injector wires from the db37 connector to injector connectors and no breaks in the wires.
I attached a fuel injector noid light on fuel injector connector and it lights up and blinks when starting. Fuel pump primes. I also checked spark and I'm getting it to light up.
I bench tested the ECU with a stimulator....touching pin 21 and 22 to ground to check injector circuits and that passed. injector led pulses on the stim when turn the pots.
When I put the ecu into fuel injector output test, all i get is the pump to go ON but no output from my fuel injectors.
Any suggestions on what to check? Posted two no start files and msq....
