Are your plugs so fouled out that they won't fire?

1988 K2500 5.7l. Is not firing.New coil,new distributer,new plug wires.
the truck just quit while driving like i turned the switch
I also checked the ignition switch. The rotor button is turning while trying to start.
Do you have power at the coil and ignition module when the key is turned to "Run"? If the wire harness is in good condition, power from the coil also powers the module. But wires can break, insulation gets damaged leading to wire corrosion, etc. For that matter, you could have popped a fuse protecting the ignition system.New plugs
Huh? WHAT is a "bypass ignition"?It is a bypass ignition.

If you still have fuel spray but no spark, the ECM is getting an RPM signal from the module.
