If yours does not have the round port under hood then you may have a faulty EWS module itself. Either way a proper EWS delete tune should solve it, but there's no reason not to simply get EWS to work since this car was originally ms43.

I hear you and agree, except that I flashed my factory ECU back to virgin+EWS delete+DS2 this afternoon, reinstalled it, and no joy. Everything turns, but no hint of any start.
I also just attached jumper cables directly to the battery negative post and 2 places on the engine, the exhaust manifold and the left ring on the front of the head. Does the same thing.
If I push the gas pedal while cranking it does make a different noise too, so I feel the throttle body is working.
My 2003 doesn't have the round plug as far as I know, plus with the EWS delete I shouldn't need it. Plus, my understanding is that EWS is what sends the second signal to the starter solenoid telling it to engage the flex plate gear. The engine is rotating.
I'm all ears on ideas because I'm all out of them.
