Question about 1990 Geo Tracker

1 Answer

Hard to start

My 1990 Geo will not start unless the gas pedal is on the floor before the key is turned on. If I do not put pedal to the floor the GEO floods out. What could this be? 1.6L 4 cylinder Is it part of the choke??

How to adjust 95 geo tracker clutch


engaging?
you meant dis-engage im sure.
pedal up is engaged,
pedal at floor dis-engages it.
my guess, is the clutch drags unless i push the clutch pedal 100%
to the floor.
1: bad cable is 90% cause. non last this long.
2: no free play is way too loose.
3: broken lever on the pedal top. caused by #1

My 1990 Geo Prizm GSI will start, but it won't keep running when the weather is cold.


Sounds like the automatic choke control on the carburator is shot! It is stopping the proper flow of gas from getting to the engine...replace it! Also make sure you have recently replaced the fuel filter; moisture in the gas will stick to the filter and freeze up making it hard for gas to get through!

You need to replace the brake light switch, it is located above the brake pedal and is actuated by the brake pedal arm.

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.
