Question about Geo Prizm

4 Answers

I have a 91 Geo Prizm. In colder weather I have to hold the ignition key 'on' and wait for 1 to 20 seconds (depending how cold it is) in order for the ignition to kick in. The colder it is, the longer I have to hold the key to 'on'. This has been a problem for at least 10 years. It has had new starters over the years which does not change the problem.

    Perhaps I was not clear. There is no ignition at all until I have held the key in the on position for a period of time. It starts fine once I get ignition.

  • atulip Sep 17, 2010

    The ignition key must be held in the full position for a while to get it to start before I can release the key to the normal position. This only happens when it gets colder than about the 50's.

    Nothing happens at all while you hold the key fully on. There is no ignition whatsoever. When it does finally fire it starts fine. It seems like a contact somewhere is not connecting because of the cold, the colder it is, the longer you have to hold the key.

  • atulip Sep 18, 2010

    I get NO IGNITION at all unless I keep holding the key fully on. Again the colder it is the longer it takes before the car fires. It starts fine once I get ignition.

    No I have never had the ignition switch replaced. Is there an ignition module involved that may be causing it? Or is there just the switch?

Yes the problem is related to ignition switch.The switch is not getting the car to start quickly.So replacing the ignition switch should help.Its a 12 volt switch,so get the volt checked to confirm the fault.As per the problem its indicating switch problem ,but in some cases both the switch as well as the ignition lock cylinder causes this problem.So in that case the ignition lock cylinder also has to be replaced.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

I would suspect the ignition switch is the problem. Have you replaced it? I am talking about the switch and not the key tumbler lock.

Does anything happen at all until the engine cranks? Or does the engine crank for 20 seconds? I am not sure that I understand what is going on fully.

    OK. I don't get to see any of the comments that you have put in until you comment to me. Sorry. It is the ignition switch that is down in the steering column. Or the starter solenoid. The starter solenoid is easier to change. So you might start there. Or if you want to take the solenoid off and take it in, they will test it for free. That will tell you if it is the solenoid or the starter switch.

Hi, this is normal in cold weather conditions for most vehicles the oil is cold and thick as well as all other parts, next time you buy a battery see how many cold cranking amps it has if you can get a battery the same size with more cold cranking amps you will see a big difference in cold weather starting.....

    All batteries are weakened by cold weather, and take time to start.
    You must have a fresh known good battery that is now fully charged during cold weather. To check it, start your car with it, then DETACH THE BATTERY every time the car is parked.

91 tracker the revs high as soon as its started?


old post.
ALL DO THAT.
BY DESIGN. 91 is 8v TBI and does it more,(laws here force that with wet inducted fuel TBI (read nasty smog engine,cold)

COLDER FAST TOO.
turn key in say alaska (yah cold. start say 2000 rpm and in 3 to 30 seconds, drops to say 1500, (dash pot did that by ECU commands)
then the IAC rules the roost a thermal device that opens even more at -10c , and races, until it hits 158F and closes
then ecu wakes and controls idle speed by software and regulates at 800rpm
all do that. Brand new. or in perfect running order,

if the 91 ever gets vacuum leaks
it will race fast hot and cold
with full power and no misfiring.
with leaks like that the ISC VALVE GOES OUT OF CONTROL.

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!

How do I remove the key cylinder from the ignition of a 1996 Geo Prizm? The Key will notturn all the way


Jiggle the steering wheel to release tension. If the key turns at all, it is not the ignition that is holding it, but the steering.

After unusual below freezing weather here in california my 94 prizm is idling really rough and sputters in gear what might be the problem


Sounds like water in the gas. Colder temperatures can lead to condensation in the gas tank. Water then enters the fuel line, causing sputtering, rough idle, and occasional stalling. Try a bottle of Dri-Gas or other similar product with your next fill up. If the problem persists, you may need to change your fuel filter.
