HELP!! Please!

I have a 2002 3.7L Jeep Liberty, blew the head in it and put another motor in it. We have had it replaced the computer, all the O2 sensors. It would idle rough and stall out with reducing speeds, like when turning corners. Changed the power steering sensor, it was still acting up. Just changed the PCM and now it will only run for 30 seconds then die. Code P1685 is coming up. Any suggestions on what to now? Any help would be greatly appreciated!

Re: HELP!! Please!

I donīt know the Liberty, but it probably also has the SKIS system (sentry key immobilizer system). When you changed the PCM, was it programmed with the SKIM code? If not, then that is your problem. (P1685 means that the PCM didnīt receive a valid key signal from the SKIM)
