Injectors filling cylinders with key on engine off.

After pulling the heads on a 2006 6.0 I noticed that someone had used a fire extinguisher on the drivers side around the fire wall area,ipr valve was covered also. I'm thinking that the heat screwed up the plastic coating on wires in the harness but didn't effect anything until I moved them to remove the heads. Fuel is going into the cylinders with the key turned on and engine not running causing hydro lock on both sides. Thinking injectors are being commanded to stay open. Doe's this sound right to anyone else?

Also before starting ficm had only 40 volts replaced and still 40 volts and kam volts were low. after starting ficm volts went to 48. Can't here glow plug clicking when turning on key light comes on then back off as normal. replaced glow plug module and no change.

Injectors are from the dealer. yes idled great for about an hour. drove great for about a mile and a half then shut down. after cooling engine would start but run rough and started smoking out the exhaust and around they pipe connection coming off turbo. towed it back to shop with a chain. had the key on to steer. once i got there It was hydro locked. pulled injectors on right side and bumped starter fuel blew #1 but still hydro locked on drivers side.

I'm thinking a bad wiring harness allowing injectors to stay open. Is that possible.

Head bolts had stretched and damaged both heads. they were milled .008 below min standard but the repair shop said they would be fine.

i don't think commanding the injectors to open can hydrolock since you have no oil pressure to actually fire them

but it is a good question cause you verified it is fuel in the cylinder SO hopefully someone chimes in
