Hi all havent been here in a few, got a puzzle whit my 97 Neon.
It is throwing codes 12, 22, 11 i know what they all mean thats not the question.
I have replaced both the cam and crank sensors it was running great and i have not had the battery disconected for some time way over fifty key on cycles.
On the way to work it stalled, if I wait about 5 minutes it starts again but only runs a few minutes then stalls. I got it home (about 5 miles) each time it started it would run for a shorter time. When it stalls gas gauge speedo all the dash shuts down like the key has been turned off or something. The codes which were cleared after replacing the cam and crank sensors have come back and now the 12 code shows.
Could this be a short to the pcm or a ignition problem at the switch?
Anyone have any ideas or suggestions? or had this happen to them?
if so let me know i have done alot of testing and tracing and still not found the culprit.

 

Well i guess its not a question or problem any have run across, or maybe i havent been around long enough to get a responce.
just hopeing to get her moving down the road again my Ram is eating a whole in my wallet driving it back and forth to work lol.
OK so im back to testing and cheking geuss i'll run thru the whole system once again and hope to find it. Intermitent shorts are a bitch.

Thanks

 

i freakin HATE electronics!!!

 

Wait, isnt code 12 simply the battery has been disconnected within 50 starts ago?

 

Yes 12 is battery disonect from pcm in last fifty cycles.
Seems now after testing everything i can here it is down to a fuel problem.
Had it jacked up to test signal to crank sensor and vooormm she started no problem.
ran it up and down the road a few times and it started to stall out again, so i droped the tank and found the fuel filter the life time one lol was restricted.
So now im down to changing entire pump assembly as i cannot locate the screen anywere by its self as of yet.
Anyone know were to get one?
or can i just clean it out and reuse it 215.00 or so for the pump seems a bit excessive to me for just a filter.

 

What about the code 11...the timing belt code? Maybe your timing is off.

 

OK this is to let you all know it was a short in wiring harrness just at the split near cam sensor. Not broke all the way throw but just enough to heat up under load and short out causing the codes all fixxed and happy.
Just goes to show perserverance pays if you got it, thanks for all the advice and all the great reading.
