The problem is with the tone ring, the reluctor on the crankshaft. 2002 has a 16 tooth reluctor ring, and the 2004 has a 32 tooth reluctor ring. But there are ways to make the engine run, I've looked it up before, just can't remember exactly what is needed.
pull the tranny as well...then driveshaft length may be a concern~
You'll have to change the computer and wiring harness.
