QuestionQUESTION: Ok im going to be as detailed as possible for you. So about 2 weeks ago
i got in a front end collision. I ended up replacing the tension
pulley,cooling fan, ac condenser, radiator, upper radiator hose, belt for
the alternator,thermostat....and the fan . Now i burped the system the
engine was running fine for about 45 minutes or so... I decided to take
it for a spin i drove around 5 miles worked fine everything was perfect
then i got into my neighborhood and the car just stopped *all the
electronics in the inside worked*, thought that was strange put it in
neutral started it again fine, so i decided to go around the neighborhood one
more time then it stopped again. So since then i have replaced the
throttle position senor and that still did nothing!!! Is there anything
you can suggest im lost and I need help?!
Ps...almost forgot its a 1995 Chrysler New Yorker 3.5L
ANSWER: Hi Bryan,
Fortunately you can get the fault code readout with your ignition key:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the check engine light which remains "on" to begin to flash, pause, flash, etc. Count the number of flashes before each pause, then repeat for accuracy. Group the number of flashes in pairs in the order of appearance to form the two digit fault codes. Then go to www.allpar.com/fix/codes.html for a translator, or write back with the code numbers. You should always get code 55 last as it means 'end of readout'. This code readout is the most economic and efficient way to diagnose the issue. I suspect an ignition sensor is failing when it warms up, and then recovering when it cools, but lets check the codes.

QUESTION: i checked the codes and it just give me 12 and 55 which i know is the beginning and the end. I have also checked the ignition coil and it is good as well.... im not sure about the map sensor after this info is there anything else you can think of ?
AnswerHi Bryan,
Two approaches: check the battery cable clamps and check the ground attachment points of the heavy wires attached to the - post of the battery, as the collision could have loosened any of thos fittings which would cause a shutdown for example if the ground wire attachment to the engine/trans was loose. Second, I suspect the battery might have a loose connection internally due to the collision, unless you actually have purposely disconnected the battery in the last 50 or so 'on-off' cycles of the ignition switch. If you haven't done that, then the 12 code is telling you that there is a loss of voltage to the engine computer, intermittently possibly.
You may have to troubleshoot when it won't start, following an unexpected stop. Those are my thoughts so far.
