    Starting problem

    I have a weird starting problem. The first start of the day on my 1967 327/300 is usually OK, turn the key and the engine fires up like an old pro. The next start is usually different, however, say after a 5 mile drive. Turn the key, and nothing. I mean, not a grind or a peep. If you leave the key turned to the on position, however, about 5-10 seconds later the engine will suddently begin to start. I have replaced the ignition cylinder which didn't help a bit. Anyone have any ideas? Thanks as always. Jim Hansen.

    i would think the starter solenoid is heating up from the exhaust. replace the solenoid.also check to make sure the the wiring studs are tight in the end cap.

      Also look for corroded or loose battery cable connections, and make sure the cables are substantial size (gauge) wire and not cheaper Kmart-type cables. Firewall connector is another potential source of corroded connections.

        Another thing you could try to see if it makes a difference that will not cost you anything but your time is to rotate the starter solenoid stud 180 degrees to place the other half into service.
        Remove the batter cable from the starter solenoid, them remove the nut that retains the stud that the battery cable was attached to. Now you can rotate the stud 180 degrees and secure the stud and reattach the battery cable.
        Only half of this stud is used in making contact during service. In rotating it you are putting the other half in use which has not been used.

          Diagnostic

          I've SEEN the symptom Clem describes frequently (starter/solenoid being heatsoaked). As an add-on, there's a reasonably cheap/fast way to diagnose here. When the symptom occurs CAREFULLY bath the starter case with water to cool it and see if you can make the problem (no start) INSTANTLY disappear. You need to be careful because missing the starter and hitting a HOT exhaust manifold could cause the casting to crack....
