2000 Jeep GC Laredo. Computer (PCM) went bad (rotted out from NY salt) so I installed a (PCM) from another jeep, same year and model but no matter what I do the SKIM module wont communicate with the PCM. The jeep now starts instantly but only runs for 2 seconds then shuts off and the yellow security key displays on the instrument panel. The local Jeep dealer says you cant swap out computers, that I need to buy a new never programmed PCM and have them program it to the SKIM module and the ignition keys, but he says they are on national back order and he cant even get one till Feb 2012. Has anyone run into this problem? Anyone have any ideas? I need my Jeep and cant afford to be without a vehicle till Feb. Thanks, George.
