I was having issues with running rich and I really need to find out what code was being thrown but I diconnected the battery and now it won't start at all. Will I still be able to read the old codes or are they lost?

 

yes disconnecting the battery will erase codes(most of the time) once the car starts back up and runs it will usually sense the same problem and pull the code up again. since you cant start the car though that could be a big problem

 

Well that sucks a big one.

 

have a friend push you down the street pop the clutch and head right to the zone and get them to read it. just a thought

 

But I don't have any friends.. I'm kidding the car cranks fine it is just running so rich it's flooding out. Couldn't drive it down there if I wanted to.

 

It takes a while and usually a few runs before the code will come back on again. So going right to the zone won't do any good.

 

Yeah I'm going to try to get it running tonight and see if I can get a code to pop up. See what happens then I guess.

 

It almost sounds like a issue I had with my ranger not to long ago. It turned out to be a PVC tube was cracked. Check for vacum leaks and make sure all the vacum and any other tubes are connect and not cracked or loose. I would even check out the pvc tubeing going from teh pcv valve and the tube that goes from the vavle cover to the intake tube.

PS
It was throwing codes of bad o2 sensors and runing rich.

 

uhh, that erases the codes on a 95 and under cars, i dont think it erases them on 96+ mustangs. i could be wrong though, but it didnt for a friend of mine.

 

Yeah just checked for the codes tonight and there was none. Couldn't get it to run either. Oh well I have some ideas as to what is wrong it just would have been nice to have seen those codes.
