1990 Pontiac Grand Prix
3.1 v6
No spark and no pulse to injectors. 12 volts to coil
pack.
Work done to repair = Tried to remove crank sensor and top broke off
after backing out 1/2".
Tech = mw
question = Is there another way to get the sensor out without dropping
the pan?

IF there is any portion of the sensor sticking out, then you can get it out by spraying
with penetrating oil, twisting back and forth, and repeating. You will have to work at it for
awhile, but they will usually come out. The penetrating oil need to get down into the
block and loosen the carbon that is holding you up. If no portion is sticking out, need to
get a 90 degree drill and short drill bit to drill into the center of it, then screw in a screw,
then pull sensor out. Last resort is to remove the oil pan.
