    I've just ompleted a full engin re-build on thes stock 350 engin. Engin was running fine as it warmed up as I began to tune the carbuarter one weekend the engin died and wouldn't start again. The next dayt it statts up fine as soon as it warmed up again it died. No spark. Replaced the coil still no start . 5 volts to the coil with key in the run position and 9 volts in the start. new battery, new points , new starter , new coil new plugs , wires. Any ideas?

    BUICKRAT Got any treats?

    Ignition switch, maybe.

    Has to be in the switch or wiring . Probably the wires between switch and starter. You need more voltage to run . Maybve you piched a wire somwhere look between the block and trans and the starterand the engine . You might have a ground problem also.

    Are you sure the timing chain gears are properly aligned? this reminds me of several Buicks I had when the chain slacked enough that they would run cold, but die warm.

    New condenser, rotor, distributor cap?

    I had a similar issue on my 70. My car would start and run cold and then die when it warmed up. If you checked your voltages at the coil I'd guess that your resistor wire is bad. I put a balast resistor under my dash and ran a wire from the fuse block to the resistor, and then ran another wire from the other side of the resistor through the firewall, to the coil. :Brow:

    Also that balast resistor will get hot so be careful where you mount it. It will also stink a little durring the first couple runs.

    Good luck.

    TODD'S 67 Time for another Buick!

    Maybe u got it fixed already, if not this could be the problem. I had the same thing happen on a 66 Chevelle. The positive lead going to the starter was too close to the headers. When cool it was fine, as it heated up the insulation melted, exposed the copper and shorted out on the header and died. Take a look at how your wires are routed.

    Every so often, our 72 would not start. No spark, it would crank. I checked module, coil, replaced cap, rotor, etc. After a while it would start up and be fine.
    When we pulled the engine, I found the wiring near the starter was almost completely in two at one point. So I guess it wouldn't handle enough power sometimes. Maybe you have a bad wire somewhere? I would check near the starter.

    Good luck.
