1988 Chevy Celebrity car dies

First step do not disconnect the battery after it dies, lets read the codes first. here's how: Cross these two terminals as shown, then turn the key on. Count the flashes, a 22 will flash as 2 flashes then a short pause, then 2 flashes, if more than one code is stored, the pause will be longer. The codes will display three times and end with 12. Write them down and post here. This connector is right under the middle of the dash...

Connect A and B with a paper clip or jumper wire turn key on read codes. Post all stored codes!

i did code and it showed a 12 every time

i havent been driving because afarid it will have to be towed. it was running, but rough and really rich can smell the richness so i started a few times tryin to check things, now wont start and is pullin just the 12 code up. it wont start now at all.

not thinkin i had paper clip in still and tried to start and wouldnt took out and it started, still rough and rich, wont pull any code but 12. lettin run in place to see what happenes now. let you know in a few ................thanks

o2 sensors are most likly the problem and these B-I _T_C_H_E_S almost never set a code in these oldies.

ok i let run and it died, started right back up, let run few minutes and started running badly and tried to give gas and it got worse and then died, now will start but runns really bad, like not on all cyl, or not gettin enough gas maybe, fuel pump maybe, still no codes but 12

try unplugging the o2 sensor and see if it a. runs better and b. throws a code. Do the same with the ECT(engine coolant temp sensor) This is like the choke for efi cars.

unpluged o2 sensor and the coolent sensor, still runs relly relly rough now, but will start, cant give gas or will die, nothing changed when sensor was unhooked and no codes still, unhooked o2 and rehooked to see difference and nothing happened,unhooked ccoolent sensor from radator nothing happened. now though it is running at its worst though, no codes, dont know....like missin cly or something, not gettin enough gas, but will start,just runs like s;.,/

use that volt meter on the orange and black wire on the aldl test connector, is 12 volts present?

no volt meter right now,any other idea

Yes, go to radio shack and by one! I bought mine there for short money, you can not test automotive systems without one. I have two, one analog(needle) and one digital, either will work for this.
