Car throwing a code 12
Heres the story.
Took the car to work today and then to a store afterwards. Everything was running fine. Get out of the store and the car wont start. It would crank for a second, act like it caught and then just kept on cranking. I can smell fuel when its cranking so I assume that its getting gas. The SES also came on so I pulled the code and it came up 12. It did the normal flashing 12 3 times, then it flashed 12 3 more times, and then 12 again 3 times. I checked it twice and all it throws is 12. So any ideas??? I know the wires need replaced, but the distributor is less then a year old so I dont think its that but I may change the cap and rotor anyway. Thanks for the help.

Sounds like you aren't geting spark. Pull a plug and see if it's black. Check and see if you can get a white spark from it while cranking. If not, check another wire. Could have had your ignition coil or module die. I've always stuck an extra one on to troubleshoot, but if you don't have an extra one I've heard autozone can test them.
i know u know a code 12 means that everything is fine (well from what the computer can tell)... U might have a problem with the fuel pump or injector? check that the distributor is screwed down tight... if u wana rule fuel out... spray starting fluid into the intake... if it starts up, then u should start lookin at ur fuel...

Bigal is right! A code 12 means nothing. A.O.K Has to be something though, check for spark, and go from there.
i had to experiance this the other day, when my brother called me on the phone and told me the ses light came on... i was rather pissed, being 4.5 hrs away can do that to a man. I told him what to do, and he didnt blow up the car! its amazing! he got a code 34... i gotta do a search and see what the deal is on that
