SOURCE: 1996 S-10 cranks but no fire
did you check to see if fuel pump is pumping. fuel filter isnt clogged is it? but you're sure there is no spark. because if there is spark it could be air flow problems.
and you changed the ignition switch so that's not it, how about the starter. is there any noise coming from the starter when you turn key? if it isn't lined up right.
there has to be spark if you did what you said take off a wire at night and try it . electricity to start goes, ign switch battery starter(is there a relay on s10s cant remember), the alternator is here also.to coil/distributor to wires to plugs to gasoline
also it could be the wires coming from the battery , check them for corrosion. if they are really corroded could be problem. and make sure your ground is good contact. ive seen corrosion inside wires causing no spark.
just a few ideas to check.
