Engine starts

Need some help. Recently added some new planes to the hanger(Camil's AA767, & POSKY's CA767). Having the same problem on both A/C. Everything loads up great when I start FS2000. All the "bells and whistle's" seem to work right up to the time when I turn the engines. I seem to lose oil pressure,hydraulics and some electrical systems, although no failures are set. Subsequently, I get complete engine shutdown. I've seen the postings for the POSKY merge and wondered if that was the problem. The readme file from the merge download refrences FS2002. Do I need to rework the config file for FS2000 also????
