Which engine 1.0L: 3 cyl? called a G10. or called LP2 by GM. there are many parts. for ignition the CMP sensor in the distributor the ECU , generates all spark via the ignitor and it runs the coil. so what module do you what? my wild guess is you have spark problems, does it run? at all? the ECU will tell you when the CMP or ignitor is bad, did you ask it? posting symptoms always wins over show and tell parts. huh>? for sure that, not knowing the names. so here is me, rolling dice on G10s
the CMP cam sensor is in the distributor. the ECU sees those pulses, if bad sets a DTC error then the ECU generates spark , all spark by pulling the Ignitor the ECU uses the ingitor (its just a large transistor) that changes the induction coil and makes spark the ECU also throws a DTC if the ignitor goes dead to see said errors, insert the diagnostic connector jumper and crank a dead engine (is it.) for 5 long seconds. the ECU will in fact report, even 1 missing pulse in 10. here is the drawing, (all alt="were is a 1992 geo ignition control module - 453a2d33-0c48-44ef-8bd1-eaf0210724d8.jpg" />

Which engine 1.0L: 3 cyl? called a G10. or called LP2 by GM.
there are many parts. for ignition
the CMP sensor in the distributor
the ECU , generates all spark
via the ignitor and it runs the coil.
so what module do you what?
my wild guess is you have spark problems, does it run? at all?
the ECU will tell you when the CMP or ignitor is bad, did you ask it?
posting symptoms always wins over show and tell parts. huh>?
for sure that, not knowing the names.

the ECU sees those pulses, if bad sets a DTC error
then the ECU generates spark , all spark by
pulling the Ignitor
the ECU uses the ingitor (its just a large transistor)
that changes the induction coil and makes spark
the ECU also throws a DTC if the ignitor goes dead
to see said errors, insert the diagnostic connector jumper
and crank a dead engine (is it.) for 5 long seconds.
the ECU will in fact report, even 1 missing pulse in 10.
