Dont have spark 1987 buick regal 3.8l turbo

SOURCE: how to replace a crank sensor on a 93 buick regal 3.8L engine

Im assuming this is the Series I 3800? If so, if you can email me I can send you some directions on the process. Its for a Series II 3800 but it should be similar. If you cant email me, post up and I'll see what I can do.

sounds like the same thing that was wrong with the 94 GS i recently bought. found the crankshaft postion sensor to be bad. it controls your electronic spark timing which would allow it to turn over with out starting.
also does your stall when you are stopped and at idle or while at driving speed or both? mine would stall at idle and driving speeds. Changed that sensor and have not had any more issues with stalling. sensor should cost around $30-$40 dollars at your local autozone, takes about 2 hours to change just need to pull the harmonic balancer pulley (make sure to use the proper tool or you will bend the pulley) and the sensor is behind the pulley. you will gain easier access to doing the maintenace buy removing the passenger front tire and the little splash gaurd directly behind the tire held on by 3 quick release fasteners. hope this helps you out.

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.
