HEI Tach - No Start

[72lemans400]

Interesting issue. got my 455 in and fired right up. shut it down pretty quickly to hook up guages (all electrical autometer). Wired them up and now when I plug the Tach wire into dist it wont start.

Ran another wire and a new ground for the tach and still nothing.

Any thoughts?

I will check online with the tach manufacturer. punch in the tach part number or call there tech number.

I would first get a simple 12 volt lite tester, put the key on and first see if you have currant going to the distrib. something could of blown. Secondly HEI coils are in the middle of the cap. Pull the 4 small screws and make sure everything is intact. Coil may have gone south. Rule of thumb, If you have spark and fuel it has to run. Guessing its right there in the distrib. Knocked a wire off inside while hooking up tach wire probably.
