with a fully charged battery
with all 3 spark plugs removed at wide open throttle
120 psi compression is too low ,
retry under conditions described above

should be 160 psi
minimum
if compression remains low on all three after the test is performed correctly ,
suspect timing belt misalignment

since this is affect all cylinders
looking more like timing belt misalignment OR
incorrect engine oil .

key on engine off
does the CEL light up ? check engine light . if no Mr computer is not waking up . engine will never start , conform by testing 5 volt reference at
MAP sensor , see above post
if you do not have a DVOM , go buy one , yesterday .

with a fully charged battery
disconnect injector , go to clear flood , Wide Open throttle , operate starter until liquid clears from combustion chamber
then
without reconnecting injector
spray starter fluid into open throttle body .
if the engine starts then stall as starter fluid is used up , fuel quality is suspect .

what oil is in the engine ? it matters .

current OEM specification is
DEXOS1
search in google or whatever to see what that means

a better choice
is
a synthetic 5w30 or 0w30 or 0w40
with
ACEA A3 B3 A3 B4 specification

any other specification oil (than the choices above) should never be used in any Geo Metro

oils without ACEA specification and with API and ILSAC specification can never be used in any Geo Metro under any circumstances
