not S10
dead hv coil means input to coil is dead.
on this car, 1996 we look at the distributor wiring ,et al. to know what's up with that.
and fuses tops the list all EFI AND spark fuses. and ecu.(VCM)
the VSM needs 5 good fuses !!! #4,5,9,10,12
then learn to scan the VCM on any 96 or newer USA car it has
the new the OBD2 scan port (16pin) just like now.
see DTC errors cranked, p03xx errors are all that.
CMP error , CKP errors end spark for sure.
crank sensor or cam senors, 3 wire HALL sensors and there and the best kind is HALL.
the VCM (ecu/pcm) fires the spark control modlen and it the HV coil.
if CMP and CKP are not dead.
crank for 10second (release not off) and release. if either 2 sensor fail now the
scan tool tells you so.. DTC p03xx code errors.
cam must spin, and not be timed by kids.(or hold my beer)
- bad fuses (x5)
- bad cmp/ckkp (dead cam timed all wrong)
- bad spark control module
- bad HV coil
- bad wires to all this. page. of listed things.
- bad VCM (if obd2 fails consider this, if no COMMS)
- rusty or loose connectors
is
CEL/MIL/SES lamp in cluster dead it must glow keyon.
or lamp dead, vcm dead or fuse to ecu x5 dead.
hint1,use modern scan too, not one from 1996 era
many the only did 1 or 3 uSA cars then, (lack of 3 ports is why)
all; modern tools work here, 2005 year up
