Just bought a new ride. 1972 Convertible which was running great. Had purchased a Sears Engine Analyzer months ago at a garage sale. Hey I have a great idea lets see if this thing works. Worked fine. I didn't get beat for the $10. Unclipped the coil lead and a wire broke at the coil. Negative side. Spliced in less than 3 inches of wire put a new end on it and hooked it back up. Ran for two seconds and stalled. For two days now it just cranks. No Start. Cleaned and reset the points. Removed cleaned coil and the leads. Still just cranks. What am I missing? Car has a after market hood tach. (Doesn't and didn't work before) Fuse, Fusible-link, Wiring Diagram for a coil? Trouble shooting flow chart? Thanks for looking and thanks in advance for any help.

You need spark & gas to get it to run. Confirm you have spark at the plug. If no spark, then you can begin your ignition checks. If you have spark, then you need gas. Pour a small cap full of gas down the carb and see if it will start. If it starts or runs, it is a fuel problem.

Start with the spark at the plug first. You might also want to use the RED "SEARCH" feature found in the upper right of the page. Type in "engine will not run" and see what pulls up. You may get a few leads on what to check for. :thumbsup:

The negative coil wire goes to the distributor and points, when you spliced in the 3 inches of wire is the new wire of the same gauge? you can add wire that has too much resistance and you then interrupt the flow of electricity.

Make sure it is the same gauge, and then test your splice with an ohm -meter or test light, connections can be bad as crimped connectors are not always reliable, crimped and soldered is correct.

If that is all right follow,..... Pontiac Jim's advice. Gas and spark.

PS on any no start condition I always put gas in the tank a few gallons if you can, rather than go by the sending gauge could be wrong or even thinking you filled it as pump at station kept clicking off,....vapors do that as well.

sounds like you added resistance to the negative coil wire and dropped that already ballasted wire from 9 volts to like 6 volts and it won't fire
