Does it start at all couldn't tell if you got it running by your thread, If not the motor needs the 98 computer and possibly wiring harness, even tho it is a 3.8 the motors are built a little differently, I own a 94 3.8 and when I went to swap motors the only one that would work with the 94 computer correctly was the 95 3.8 and that's with having to use the 95 radiator
