Default Another crank, no start issue..

Hopefully someone can help me out and see if I missed anything.

History: Car had numerous oil leaks all around the engine. Pretty much everything was taken off the engine, cleaned, and replaced/reinstalled. New knock sensors were installed. ASC was deleted, but ASC throttle body TPS and cable motor are attached.

Problem: Car will crank, but not start.

Troubleshooting: Battery is in good condition. Starter obviously works. The DME relay is operational and upon activation supplies power to fuel pump relay. Fuel pump relay itself works, fuel pump works (bypassed relay), but the relay is not being activated by DME. Tried to start car while bypassing fuel pump relay - no good. Crank position sensor tested good (560ohms). Cam position sensor untested, but car ran fine before. I checked spark on #1 cylinder - it is present.

Things not tested: Injector signal, cam position sensor. Assuming coil pack is good - Spark plugs are new.

I am getting an ADS cable in tomorrow to see if the EWS/DME went out of sync. Maybe the DME is trashed - in which case I'd need a new one and sync the EWS to it...
