Per earlier post, picked up from shop today. Drove to work, running great. Driving home, running great although I notice volts reading less than 12v, temp gauge not working.

Almost home, a few blocks away. Going down hill. Huh, did engine cut out. Why, yes it has. Turn key. It cranks but no start. As if no spark or no fuel. Coil feels quite hot if that matters. By side of road now. (IMG:style_emoticons/default/headbang.gif)

Additional info from a, gasp!, Corvette forum ...

http://www.superchevy.com/how-to/ignition-coil-info/

from the above article:

"According to industry experts, coils have always had to compromise voltage output against current output. More voltage increases the initial ionization of the spark plug gap, but lowers the amount of current or heat that follows across the plug gap. When a coil is designed to produce more current, the voltage output generally suffers, which taxes the ease of ionizing the gap. In order to accomplish a combination of high voltage and current, the latest coils incorporate a special "E-core" winding design. This is an efficient design that more closely resembles the windings in a true transformer. In this system, less loss occurs during the transfer of electricity due to the closed core of the coil.

Given this technology, an "E" style coil produces spark with both high voltage and current. Another benefit is the coils run extremely cool, even at high rpm. This is due to the efficiency of the design, as well as the large laminations"
