Hi, my problem started when I grounded the coil pack capacitor,from that it blew the 20amp fuse under the hood and fried my pcm.from that point I replaced the fuse ordered a new pcm that was programmed with vin.put that in car starts but is only firing on three cylinders, could the new pcm be faulty?

Possibly. If you don't have Factory Alarm/Theft or Side Air Bags you don't need a VIN programmed PCM. Any 2002-2004 PCM from a 2.7L car would work. Find a used one cheap with a warranty and try that.
