Ignition problem Need help bad and quick

Have 1991 Z-28 and all of a sudden it has no power at all I read the codes and it came out with a 43 that says low voltage at electronic spark timing circuit. Does this mean the computer is bad or exactly were is this thing. Please help email me at timothyberlinski@yahoo.com Thanks guys.

"43" is for an "EST Control Failure - Spark REtard Too Long"

Check the connections at the ESC, knock sensor, and distributor. You can find your ESC here:
