When I pull the pcm fuse the meter went up real high what's going on

I started the car and it was idling really rough I put it into gear and it would not go so I killed the car and when I try to start it back up it would not start. Does anybody possibly know what might have caused this? I thought maybe it jumped timing.

Driving steam came out right side of engine .water came out over flow hose .put water drove home .since than fans don't come on .I change coolant sensor thermostat .and relays test fans off battery working fine fuses are good replace computer from under clove box relays under fans and replace water pump .plz help Larry segobia

Changed thermostat, 3 fan relays, coolant temp sensor, fans will still not come on. Ran a toggle to turn fans on and it still overheats when in traffic. If im going 50 mph or better temp stays at 199-206 degrees. Also when i first start it, it runs extremely rough for about 30 seconds once i rev themotor a couple times it stops. I have a very loud ticking like its a lifter or fuel injector
