what is wrong with my 1999 dodge durango

yes i think so it want do anything when trying to start just sounds like its locked up and when you try to start it i lose everything lights and all

Was hoping it was one of the pushrod engines! Most likely need another engine but have it checked to see if it can be turned manually.

dang thanks was hoping it wasnt the engine just dont kno whats wrong it makes asound like the engine is locked up when you try to start it and i still have power to my lights and radio and all that just when i try to start it i lose all that and it sounds like its locked up doesnt make any since to me
