94 with a vortec?? cool.
trace the lack of spark back. none at the plugs. how about the rotor and cap?? good?? the coil is new so that can be skipped. still no fire?? your pickup under the dizzy may be malfunctioning and not closing the loop on the coil permitting fire. ignition is fairly simple to diagnose as the system doesnt have that many components and all are inline. keep tracking back up the line until you find fire.
