I ran my car with old gas (2 years old) then it stopped running. I have changed the gas,plugs .the self diagnostic system check came up with code 12 problem with standby memory circuit.I could use any advice you could give me Thanks ,JohnMy car os a 94 plymouth sundance

The old gas thing isn't good, but this seems pretty extreme unless the gas was visibly bad. Did you examine or filter it when you siphoned it to be sure it had no visible water or contaminants? Anyway, its certainly worth exploring before going farther. Make sure its got clean fresh fuel. Otherwise, maybe timing belt / chain trouble?

You have asked a question which cannot be answered without a LOT more information. Like what do you mean, won't turn over? By hand? or by starter? And if starter, have you checked all electrical start systems? Have you TRIED turning it over by hand?? You should have done that FIRST before you ever tried to start it.

If you care about the condition of the engine after 12 years, you have a lot MORE work to do than worry about whether it will crank over. I had the same situation last year with a car that had sat for 10 years, and I worked on it about 2 weeks (off and on) before I ever hit the starter. (Hint: you do NOT want to suck in 12-year old gas and 12-year old oil. Another hint, pull all the plugs and squirt light oil - Marvel Mystery Oil, drain ALL the gas, oil and coolant and replace.) Oh, and by the way, when I finally hit the starter, it fired right up. Now get to work and check back in 2 weeks.

probly hav a vacuum leak--if run bad at idle--fuel pump cud be failn too--test those 2 plug wires-may b bad inside--inspect distributer cap for inside corrode--w car that age unplug computer then connect again to see if issue clears----the number can mean a worn oxygen sensor-but to confirm u need a diagnostic scan w specific equip--dont go to a dealer or use a code reader

The code 12 is just letting you know that the diagnostic system is working. Code 32 is Exhaust Gas Recirculation(EGR)failure. Check the vacuum source and all vacuum lines. Check the system electrical connectors at the ECM and EGR valve. Replace EGR or ECM if neecessary.

Have your Catalytic converters checked! Sounds like there getting plugged!

fuel pump?

Those are cylinder misfire codes. PO300 is random misfires (meaning 1+ cylinders misfired) and the other 2 codes are for cylinder #1 and 2. Did you change the ignition coils yet on 1 and 2?

Do you let the tank go to empty before refueling a lot?

stop in at autozone and have them read the codes .. it's free then repost the question with those codes

please take a moment to rate this solution thanks

Even with low miles, the truck has some years on it. Is the gas old? If the truck seemed to run fine, I would clear the code and see if it came back. Sometimes these things are just a one-off occurrence. If it continues, I would make sure it isn't running on old gas (if the truck has been sitting a while), then check the spark plugs, and go with the usual tune-up items.
