Answer
Hi Rick,
The 11 code remediation, the distributor pick-up unit, should restore the spark and the fuel pump as both require a pick-up signal which energizes the autoshutdown relay. But if the pump doesn't make a sound for 1 second when you first turn the key to "run" (which it should) then it would either be one of the fusible links in the multi-link harness behind the battery (one of the red ones that supplies current to the autoshutdown relay which powers the spark coil and the pump), the autoshutdown relay itself, of if you have spark but no pump then it would make me suspect the pump. But, the fact that you shutdown and now have 11 makes me believe the pick-up replacement will solve it. It is unlikely to have any of those separate components fail at the same time.
