Question about 1995 Geo Metro
This is a 93 Geo Prizm w/180k miles. I replaced the catalytic converter, tune up, cleaned injectors, and the car cannot pass. The car is driven less than 5k a year. I have looked for broken/bad vacumn lines, missing hoses, and still cannot find anything. The check engine light is not on. How can I pull codes to see what is wrong?
The answer is a deffinate YES, I just performed this on my 94 Prism see link provided. http://s3.amazonaws.com/2cp-images/question_images/3479/large.gif Here is a Picture of the diagnostic ports to connect with a jumper wire (TE1 and E1) This will cause codes to flash via the check engine light when the key is turned to the on position. Count the flashes there will be a couple second pause between numbers.

If the car is driven less than 5k a year than it sits for awhile, so there could be carbon buildup in the engine and intake this would cause the emissions to be bad but wouldn't through a code. you can do things like run a can of seafoam through the vacuum lines and through the gas tank. read the directions on the can and check the vacuum diagram that should be under the hood of your car to make sure you put the seafoam in the right line. to answer your question about the codes, NO you can not pull codes if the light isnt on. unless the light is burnt out and you just dont know its on. you can check that when you first put the key in the accessory position the check engine light should come on for a few seconds and then go out - so you know if the lights bad or not.
