no spark out of the coil when cranking it over testing with the coil wire OUT of the coil ?
with the key ON is the check engine light lit up in the dash ?
so you HAVE spark out of the coil cranking it over ?
ok but with the key ON is the check engine light lit up in the dash ?
you sure ?
ok can you see if the fuse called ECM1 and ECMB and ENG1 in the under hood fuse box all show 12 volts at them testing them in place through the little openings in the tops of those fuses with the key ON ?
if that check engine light is NOT on either the computer is missing power or a ground or is bad
if those 3 fuses are NOT blown and if any of them show no volts or well under 12 volts then usually the ignition switch is bad not fully powering one or all those fuses and replacing the ignition switch will correct the power to them
