Another thing that's possible, but kind of down on the list of things to
check is, the starter could be drawing too much current thereby lowering
the system voltage to where the ECU just won't function right.

I saw where one poster asked if you had tried push starting it.  If it
starts easily with a push, this could be something you might want to check.
