"Now no start after several attempts and No A2 or A6 code."

The 111 code from A3, says there is Key On +12v at the OBD LED, and the Cruise module is making a ground for the LED. But no grounding response from either the FI(2) or Ign. Control Unit(6) indicates they are both "dead".

Since that Key On +12V at the OBD is also common to all CU's (including the Cruise, which does give a code) this might be a ground-side CU problem. The ground wires on the front and rear fuel rail brackets are used by both the FI and Ign. CU's as well as the Ignition Amplifier (in my '93 diagrams). Try cleaning and reconnecting them.

At least, this post will "bump" you back up in the Recently Modified list.

P.S. This doesn't relate to the OBD code anomaly, but check to see that the camshaft turns when cranking. Sometimes the tensioner locating stud doesn't get properly seated, allowing the belt to "walk" forward and come off.
