i replaced cap and rotor button plus coil but my car will still just turn over and wont fire its a 92 rs with a 305 v8 auto any info would be wonderful this car just shut down while driving to the store and hasnt started since

are you seeing the injectors fire? If it is in fact spark related, i bet its the pickup in the dizzy, chevy has a nasty problem with these guys cracking internally, Try moving around the wire that goes to your igniton module(which could also be your problem) and see if it will fire for a second. If it does the wires in the pickup are cracked internally and make contact when put in a certain position.

the injectors are working properly ill check out this rest thanks
