A faulty ground strap can cause a no start condition but it will not cause EWS codes. The engine ground strap is on the passenger side engine mount.
If you want to rule the ground strap out, take jumper cables to anywhere on the engine block to somewhere with an unpainted surface on the chassis, or a bolt that screws into the chassis. The lift point to the chassis ground point usually works well.

Keep in mind that will test for one possible failure mode, it won't indicate every issue with EWS.
You do not need to be cranking to align ews-dme. Key needs to be in position 2. If it's in the wrong position it won't even hook up to INPA or whatever reader you are using.
If you have EWS codes still present after alignment then that should be the focus.
