All,

Well... the battery checks out to be in very good condition with "a lot of life" left in it... so I guess that nixes the bad battery theory. I believe Terry and co. is on the right track with regards to bubbles in the fuel system. I am looking forward to receiving the new prefilter/seal and changing both filters out. I still don't understand why the possible air bubble creates a problem with lower temps, but not high (can someone please explain this to me?)

The plan now is to change out the filters, then try starting the car at home (which is generally much colder than in town) some morning without using the block heater.

Also, if there is a proven method used to purge any bubbles in the system, I'd appreciate the "how to" on that as well.

THanks all!
