The engine barely starts when it does start it misfires badly?

My good running vehicle listed above was recently stolen and recovered. The damage that ensued was a broken door lock cylinder and damaged ignition cylinder. A stolen battery and battery cables were cut at the battery. A punctured gas tank. Also fuses and relays under the hood in the fuse block were missing as well as the catalytic converters and rear o2 sensor to say the least. Since then, I have replaced the battery and the cables. Sealed the punctured fuel tank and filled it with gas. Replaced the fuses and relays. Also have replaced the ignition housing and ignition lock cylinder. I proceeded with the pass lock relearn with the new key cylinder and it seemed to work fine. It started no misfires and running smoothly I shut it off and restarted it 3 or 4 times after that night. The next morning, I loaded up the parts to take to the muffler shop cats and 02 sensor.
It barely wanted to start at all and when it did it misfired really badly. I've checked the fuel pressure, it’s 60 lbs. And have changed the distributor cap and rotor. It seems to me that the injectors are not firing correctly but I have no security light on. Cylinders 1, 3, 4, and 6 seem to not respond when pulling plug wires while running. I'm thinking of ordering another ignition housing and cylinder. Please help.
