Helly everyone. First time posting. Just bought a 67 Chevelle Friday. I noticed a short in the lights so I tried to do some testing with my test light. Well, I must have hit the wrong wire and I got a spark. Before this, the car started fine, but now it turns over but will not start. The car now has a 350 with an electronic ignition. I checked the fuses and didn't find any bad ones. I also put a new coil in it, and that wasn't it. Can anyone help? Thanks
67 chevelle not starting

Do you have 12 volts on the B+ distributor input wire? The distributor should have 12 volts to ground in both the start and run positions. The B+ connector is the outer front connector. It is the one that looks brown (should be white) in this photo. http://www.chevelles.com/forum/Forum22/HTML/001906.html
I checked this, with the key on, and I don't get any reading. A friend of mine told me to check this, he said wire under the cap where it says 'tach'. I'm also glad you enclosed the photo just to make sure I understand which one. The answer to the question is: I don't have 12 volts here.
Your friend is mistaken about the tach connection. You won't see anything there. You can actually take the B+ wire loose from the distributor to measure it. Be sure not to short it to ground. The tach B+ wire is an add-on wire. It should have 12 volts on it when the key is on. Part of the HEI modification.
The other end (normally) goes either through the firewall to the fuseblock or to the bulkhead connector near the master cylinder. I can't tell from here.
Follow it back. It shouldn't be inside a harness bundle. Maybe a popped fuse?

John,
Last night, I took the B+ wire loose and didn't get a reading. What I think happened is I shorted to ground the headlight switch and I can't find what I shorted. You would think it was a fuse, but they all look OK. You are correct, the wire from the distributor goes through the firewall. I don't recall where exactly it goes to, but I'm going to look and follow it tonight. What I plan on doing on the way home from work is to buy all new fuses and replace them. Thanks

Two things you need to verify for a startup since you haven't changed anything: Spark & fuel.
Make sure you have fuel from the carb. Stick your fingers in the venturi and push on the lever to shoot some gas on your hands.
Then either check to see that your plugs are firing by pulling out a single plug and checking for spark while a buddy cranks it or put a timing light on # 1 and see if it lights while a buddy cranks it.

If You don't have 12 volts at the Dist. "BAT" terminal you for sure won't have any spark
You are on the right track tracing that wire back to it's source
Sometimes when a connection or splice is very poor and just barely making connection, even a very slight sparking of it to ground will finish it off

oops, sorry John, your reply wasn't there when I started mine (and stopped to help the grandaughter get her toy car unstuck from behind my chair)
No problem Dean. Starting car repair already on the next generation?

She pushes it in behind the chair and crys when she can't get it back out
Hey we can talk back and forth without bringing the topic back to the top
