its not the worst, not the easiest job to do, but can be done with hand tools. you'll need a puller and the right bolts for your balancer, the bolts should be listed in this how to. http://www.grandprixforums.net/showt...e+crank+sensor

id be testing the fuel pump, (if that checks out) then watch how it acts over the next few days for the tach to drop before it stalls. if that starts to happen its the crank sensor for sure.
