there is a special tool for this job but I have cheated on this but you ned to be careful when doing this.The wishbone shaped mount on the front going from motor to front of vehicle, remove and it allows the motor to tilt.

SOURCE: 91 Buick Park Ave won't start

i just came across this problem myself the other day. i have a 91 buick park avenue that sometimes won't start. i checked several things out like cable connections and coil pack etc. etc. come to find out it was the wiring that came off the coil pack and connects to the crank sensor. the wiring that ran over top of the water pump had finally heated up so bad the coating on the wires had melted and when the engine got hot enough the wires would come in contact and send false signals to the computer not letting it start. after the car cools down and the wires contract it would start. so check the wires from the coil pack to the crank sensor to make sure the wires are not melted together.
