How much would it cost to change a crank sensor on a 97 gst ? Gotta guy askkn 250 .. Good?

 

Not a bad price for the work involved, but its much cheaper (obviously) if you do it yourself. Its the same procedure as changing the timing belt, except after your remove the timing belt, swap out the sensor before you put everything back together. You might be able to get the crank sensor out without removing the belt, but I wouldn't recommend it.
