1991 Geo Tracker only starts with starting fluid.
91 is 8valve TBI injection.
it is flooding.
the starting fluid is more combustible and starts a flooded motor.
kinda like adding dynamite to bbq lighter fluid.
hahah
ok,
try a tune up.
then try holding gas pedal to floor, this is super secret unflood mode and cuts fuel injection.
the issues why its flooding, not starting is normal for that condition.
so its:
1: bad need of tune up
and or
2: leaking injector.
the former you can figure out.
cap/wires/plugs /rotor, filters, there i said it.
or
this car has a viewable fuel injector
one an do 2 things with it.
key on five times , or 5 seconds on, not cranking
and other person looks down throttle body neck
yes, off comes the tube on top.
and makes sure the injectors dont dribble full time, key on.
or
the ECT is bad.
or dash pot is not opening at key on crank.
or
cold start, IAC is clogged.
complex it is,
it will take hard work to check everything.
