99 Intrigue crank sensor code

Hello group,
I have a 99 Olds Intrigue, 3.5 L double OH cam engine. About 1 in 3
starts, I have to crank the starter for several seconds before the
engine starts. The other times, it starts normally. When it is hard to
start, it sometimes hesitates when accelerating and then is OK until the
next 2nd or 3rd start. A "crank sensor" code comes up after a few hard
starts. Would a crank sensor be intermittent as described above? Would
replacing it solve the problem? Any help appreciated.
Thanks,
Gary

Crank sensor's have magnets inside. The magnets over time can get weak.
You might also check the wiring circut for the crank sensor.

I would think that, in general, it is more likely that the connection is
intermittant. Try cleaning that first. (I don't know, off the top of
my head where it is on that engine.)

It's behind the starter motor, close to the exhaust manifold, behind
the engine. It can only be reached from under the car.

The senor can only be found in dealers for about $120. Because the
car still goes without it, though not optimally, I'd advise you to
wait two weeks for the part (#10456594) buying it at
http://gmpartsdirect.com for about $60, including S&H.

Every 3.5 Intrigue I've worked on with this symptom (many) needed the crank
sensor.

Any tips on replacing it to a weekend mechanic?

TIA

You'll have to do it from under the car. Putting the car on ramps may be
good enough. Disconnect the battery. Remove the plastic splash shield.
Unbolt the starter and let it hang down. You'll probably need a long
screwdriver or some such to get the connector off the sensor. There's one
10mm bolt holding the sensor in. You'll need a swivel 10mm socket to get
on it. Unscrew the bolt and pull the sensor out of the block. (This
procedure is definitely more difficult than it sounds here, and there will
be little room to work).
