1995 Chrysler Cirrus 2.5 engine 125k miles
History-- had a start then die condition then start and run ok from the time we bought it used.
Had a scan done and was told nothing showed up and replaced timing belt. Same day timing belt and scan was done the alarm went off and could not shut off, chrysler cntr. Had to disconnect auto door locks to make it driveable.
About 2 months later it died while driving and would not start until it sat for an hr or so, but would die in less than a minute, now wont start no spark.
I replaced crank sensor--still no spark. Next is the distributor/cam sensor.
Can hear fuel pump kick on when key is turned.
Did the key on-off-on-off-on and get codes 71, 33, and 12.
71--5V problem, I checked sensors on that circuit and all at about 4.8 to 4.99. The PCM 5V ok too
Bought a code reader but it says unable to establish connection---It is a CAN OBD I and OBD II reader.
Tried a used PCM from junk yard same result. Was told by salvage yard people that the idle air controller motor is possible damaging the PCM causing the "connection" problem. I think I got a bad PCM from them and they do not want to replace it. I have gone thru testing procedure per ALLDATA. Com and it leads to bad PCM.
But if I can get codes by way of key on-off sequence why is PCM supposed to be bad?
Any suggestions about the no spark and my code reader not able to establish connection will be much appreciated
By the way under the hood it says car is OBD I compliant but DLC is under dash as if it was a OBD II is the right? Could BCM be causing me the problems and how to test BCM? Thanks
have the same problem?
