p1684 just means the pcm's power source was disconnectted less than 50 key
cycles ago.

Sounds like your battery went flat.......battery charger, battery and
alternator tests would be a start to fixing the problem I guess.

Thanks for the reply propman, but the batt was on the charger all evening
after It would not start. It's either not getting spark or fuel. I can
hear the fuel pump working. It almost fired after a shot of ether but can
was empty. I'll leave the charger on all day tomorrow as I won't have time
to work on it.As for the code I remember last week when it was over 100
degrees in Chicago it took a couple of cranks to fire, maybe thats were
the code P1684 came from.
