    When it wont start check for spark at the plugs!! If spark ok, good and hot, then it must be fuel related. Also it would be nice to have a fuel pressure test gauge hooked up at that time! Any codes? May have a crank sensor problem. If it aint getting spark, forget about fuel!!!!!!

    on my gmc I had a crack in the plastic top of distributor. I changed that and about a week later it started again. My son in law came by that evening and we were standing in front as my daughter cranked it. The coil powerpack started arcing a spark to metal next to it. We replaced coil pack 25 bucks from auto salvage yard. Do not forget to cake on electrical connection gel on engine side of coil pack, it prevents engine heat from wearing it out pre maturely. That was three years ago...solved my problem.

    Does not have a coil pack. Coil is in the distributor which has been replaced as stated.
    Good thought though.

    You may be right and of course I agree with Wetry as that is the terminalogy that my father passed down to us.Make sure you got good fire. In the old days they used to say if your dash lights dim or flicker check alternator and clean battery cables. There is a draw somewhere. On newer stuff electrical sometimes gives me a headache. So I do what I know and before I spend the big money I ask alot of questions like you are doing now.
