Front tank fuel pump only operates in crank mode filling carb and allowing
engine to run untill carb empty.  Will restart and same thing happens.  The
rear tank pump is dead at all times.  This problem happened when attempting
to start after it sat for some time.  We had to replace a starter and
battery and while checking roll over switch (bypassing it) it did not start.
However all of a sudden it decided to start and run long enough to pass CA
smog (dyno test) and return home about twenty miles away.  It has not
started since.  I have no wire diags and think it may be the loss of a
ground or connection.  Any clues to finding usable diagrams or where to look
for connectors.  Thanks in advance for any help, would like to go out on
dads day for trip.
