what year is the replacement engine?it is well known with recyclers that you CANNOT change between generations of engines meaning a 2000 vehicle must use an engine that is compatable with it's computer, we changed the tone rings around 2004 from 16 tooth to 32 tooth on the crank these engines ARE NOT INTERCHANGABLE EASILY to swap the tone rings on the crank you need to disassemble the engine.did you compare the tone rings between the 2 engines?

they looked the same
Expert:  bill replied 1 year ago.
what looked the same?the engines? all 4.7 engines look identical on the outside i need to know the donor engine's year before i can help, also did the donor engine run? if you bought it from a recycler they are required to put the vin of the vehicle the major component came from on the receipt, i can use that to determine the original vehicle and if it's interchangable
