    Yeah, I was just joking. She's actually a big help, and more importantly she loves to see me indulge in my Buick habit. Tough to beat that.:TU:

    Rolled the dice today and crapped out. Reconfirmed TDC. Not getting any spark. See Sparkys' Corner for info on that.

    I'm in Marion. Ya wanna come haul it away for me?:Brow: Vacation is over, back to work tonight, so I'll only be able to nickle and dime on it. Shouldn't take much more than that. I'll just keep thinking that. I think I'll be glad to get back to work for a change. What a week...

    Well.. thats not what I was thinking... but OK.. I'll pick it up tomorrow!! :Brow:

    You're only about 45 minutes from me. I'd be glad to swing down that way sometime and help you tinker with it. I probably won't be much more help than your wife, but sometimes a "fresh view" can notice something obvious that you've been overlooking..... like... did you remember to put spark plugs in? :spank: :pp
    But seriously..... let me know if you don't get it figured out.
    I even bring my own beer......and Buick! :gt:
    :beer

    I'll keep you in mind. With any (or a lot) of luck I'll have all my ducks in a row after a week of not dealing with it and things will go a little better.

    there is an easier way to confirm tdc than pulling
    the v/c. unplug bat + wire from dist. remove #1
    plug, hold your thumb over spark plug hole and
    have your helper bump the starter. when the piston
    comes up on the compression stroke you will feel it
    then turn your crank backword to zero. then you are
    at tdc

    I have one of those whisles(for dummies) that screws in the hole and tells you if your on the compression stroke. Pretty handy and I can do it by myself.

    Andy - Have you verified that the coil is indeed good??

    I noticed you suspected the module 'may' be a problem....I would also put the coil high on the 'suspect list'!! Especially one of those 'in cap coils'!!!:Dou:

    Might try swapping a known good coil.

    Yeah it was brand new, along with everything else but the condenser(?). I'm going to get everything tested tomorrow and replace if I have to and try it again.

    The only other things I can think of is the pickup coil and the roll pin that holds the dsitributor gear on. I've had both fail.

    The pickup coil kicked my butt. It's not supposed to ever go bad. They do. You have to disassemble the entire dsitributor and take the shaft out of the housing to replace it.

    The roll pin was another thing entirely. I sat in my car, and it cranked and cranked....no fire. What had happened was a bit of casting flash got into my oil pump, from somewhere. The chunk, about the size of a tomato seed, jammed the gears up in the pump solid. The roll pin did it's job and sheared off, stopping the engine immediately. I could crank that thing all day with a good distributor but the rotor would never turn since the drive gear spun freel. Needed new pump gears, too:gt:

    Well, I had fire (flaming backfire) initially., so I'm pretty sure its one of the components. Checked the roll pin too. Pick-up coil....I hope not. How do you check that...just in case.
