Where is the spark igniter on a 1992 geo metro

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, (alldata.com, has it , log in and read)

need help ask..
where is the ignitor or ECU?, which is it?, do say and can answer.
ecu
the ECM is located on the driver's side of the vehicle behind and below the instrument panel.
the ignitor is near the ign, coil
each generation of swift/metro has the ignitor in the ECU or outside
and varies by engine type. not stated.
the below is G10 ECU.
CMP, ECU, filter, ignitor and Ignition coil at bottom

Check the crank shaft position sensor.

Failed Fuel Pump or Relay Bad

On GM inline engines,cylinder #1 is the one closest to the front(pulley)end of the engine. If you pulled the wires off the distributor/coil pack,and don't know where they go,put one wire one at a time and crank it.If it doesn't backfire,repeat until it starts.(this is only easy on 4 cylinder or smaller engines)

Make certain you get the right Distributor. There are two different types Electric and Vacuum timing-advance versions. The coil is as simple as the plugs. But be ready to shell out some dough.

Before you pull the distributor out, make certain the rotor is pointing towards some area in the interior of the engine bay you can point the new one in easily.

Then it's just pull and plug wires! Have fun !!!!!!!

may be low on fluid as that wont shift the pistons in the valve body of the transmission
due to no fluid pressure!

check the timing belt it might have broken

DId you remember to push (depress) the small, square button to the right, first?

Sounds like your timing belt has slipped or broken, bad news is it is a interference engine, talking rebuild if that is the problem.

The firing order is 1-3-2,   distrubtor rotates counter clockwise. looking at engine from front of vehicle cyl. # 1 will be on your left cyl.# 2 center and cyl.# 3on your right.
