F6B would not start!

[53driver]

John in northern MS is replacing his ignition pulse generator this weekend. He had a 19 flash error code and it sounds like the same problem. Turns over but won't fire.

Code 19 is NOT the Ignition Pulse Generator!
It's the Crankshaft Position Sensor.
What does he hope to achieve by replacing the IPG?

Curious,
Steve
