I have a 1993 S10 blazer tahoe 4x4 with votec 4.3. it has been running great then on the way to work one day it just died, like the key was turned off. i put new coil, cap, rotor, and pickup coil and still no fire to plugs. i'm stumped. please somebody help!!!

 

Get the Ignition control module tested

that provides spark also

Make sure you go with ac delco

 

+1, then I would do a fuel pressure test just to be sure you don't have any other problems lurking.
