I"ve been having the same problem...cranks, but won't start. Until yesterday it would start after about ten minutes, or after it warmed up a bit outside, but I finally gave up trying. After checking the distributor we finally figured out there's no voltage from the battery to the distributor. Today we'll be checking switches and relays. Any other ideas would be awesome. I continue to search....
Everyone we talked to today said to replace the distributor, so I ordered one on ebay. I'm keeping my fingers crossed.
