My ol 99 5spd was totaled about a month ago. An i purchased a 02 6spd that sit up over a yr an while trying to get cranked back up it through code 1689 i did all the stuff to fix that code an still wouldn't start . So used the vp44 off the 99 an it firedd up. The one thing i noticed right off was that it dont acceralate like the ol 99 did. Is there a difference in the 99 pump an the 02 pump?? Other than that everything seems ok runs great.
