Thanks Scott - I hear the fuel pump clicking on and off - so i think it's
definitely electrical.  Previously, I had to reground the wire on the left
of the engine block (the bolt where it was grounded broke off), so I wonder
if my new ground wire is not working OR it's just a bad fuel pump relay.
Will try replacing that to see if it remedies the problem.  Just curious -
where's the best place to install a fuel pressure gauge?
