It just died while driving

[427TJ]

Okay, my Camaro is up and running once again! I'm not sure exactly what the problem was but I replaced the old (original, I think) starter and solenoid with an Autolite unit from the parts store, new OEM-look coil from Rick's, new OEM-look spring-clamp battery cables from Rick's that have the ground pigtail off the Negative to the fender and the lights pigtail off the Positive to the junction block on the rad support. I also put heat wrap sheathing around the wires from the ignition harness to the solenoid so they don't cook on the exhaust manifold and I put a heat wrap around the starter so it won't get heat-soaked in summer traffic. Started right up and started several times once it was good and hot so I guess I fixed whatever it was! My Camaro is my back-up car for Goodguys this year in case my '55 surprises me with some "issue." Thanks guys for the help! x 1,000

Good job,

Happy cruising!

I would still put a dwell meter on it and visibly check the points. Can't hurt!

Points and condenser checked out Sam, thanks! I think I found the real culprit. A while back I bought a new Jet Q-jet with electric choke. (I ordered manual choke but they sent the electric so I kept it and installed it.) My buddy was over at the house and he hooked up the electric choke's power wire to the coil. I thought that was a bad idea but he said naah, it's fine there. The electric choke functioned properly for a few months and then slowly stopped functioning and the car reverted to fussy start-ups and poor cold idle quality. I didn't think much of it because the engine has well over 100k on it and it's just an old car. So during this recent crap-out I replaced the coil with an OEM-look stock replacement coil from Rick's and disconnected that damn electric choke wire that had always bothered me because it was connected to the coil rather than its own dedicated power source. As I've said above the car now starts and runs like a real champ. Smooth cold start, smooth cold idle (for a 110K 396/325) and the electric choke is not hooked up. I think I may have fried the old coil with that choke wire siphonong-off current? That might explain the tach needle bouncing a few times after the engine quit at speed on the freeway? Any comments on my hypothesis??? Could the choke wire drawing off the coil cause coil failure or at least diminished coil performance?

Now I'm going to remove the electric choke setup and see if I can re-mount the old manual choke parts.
