Cold start problem -- MFTS (multi-function temp sensor); not getting the
   signal to make it rich on start-up

cranks and cranks -- bad seals on the injectors let the fuel pressure
   bleed off over time (several hours or more); it takes a bit of
   cranking to rebuild fuel pressure. Remedy with new seals (or new

puffs and puffs - (guessing here) vacuum leaks?
