No. The 3.1 is a 60 degree engine and the 3.8 is a 90 degree engine. Everything is shaped very differently. The best you can hope for is that it won't fit. More likely youl damage the flywheel and could crack the transmission.

What causes a 1998 Pontiac transport to run hot and engine shuts off
Yes
Changing a starter in a 1985 Pontiac Sunbird is not very difficult. The car will first need to be jacked up. After the car is jacked up, locate the starter. The wires will need to be taken off the starter and labeled so they can be reattached to the new starter. The starter is then taken down by using a ratchet to take of the bolts. After the starter is taken off, the new one can be put on.
