Did you get a code for crank sensor? Do you know the history of the car or when the water pump or crank sensor was last replaced?
Front crank seals are on the Shosource website.
I cannot find a CKS. Anyone know where to find one?

My experience is that getting soaked is not the primary issue for failure. The issue is that eventually electronic parts fail, and heat typically speeds that death. Since the sensor is attached to the engine block, it gets heat cycled regularly, and eventually it quits working.

No code, yet.
I'm the third owner, car was purchased in charlotte and never left the piedmont here in NC. Guy I got it from said everything had been replaced within the past year. He showed me a bunch of receipts which don't mean anything to me.
I'm in the process of changing the timing belt, tensioner, front seal, oil pan seals(leaking), valve cover gaskets(back one leaking), cam sensor, and water pump. That way I know its actually been done. He had reciepts for all that stuff getting fixed or replaced and then some, including a crank sensor.
Yeah Shosource is pretty nice and I will be purchasing from them but I'm just in the habit of looking locally first.

Is there such a thing as a datasheet on the original CKS? I poked around a bit this morning but couldn't find anything in any of my service manuals. I find myself wondering if we couldn't use something like the MLX90254 sensor with a custom epoxy housing / mount.

This is something I am hoping can be discovered without having to run an aftermarket ignition system (MSD, MoTec, etc). Way outside my expertise but hopefully not everyone's around here. Or we could try and beg for a small run from one of the mfg's. Not sure we can come up with enough members interested to pull that off.

Is there a magnet involved? Somehow it senses the shutter wheel with spaces and solid sections. And signals to the distributer system either the solid tang or the space as it rotates by the sensor.
If I understand this correctly, this signal is checked by the cam position sensor.
My question is, can it be arranged so that the cam sensor runs the whole thing; with no check from the crank sensor?
On another note, is it possible that crank sensors last longer in northern USA and Canada, as my crank sensor has 200 K miles and counting. But lately, it has been a winter vehicle, so the electrical side of it would not get too hot, at least in the last 10 years.

Firebat is trying to develop a set up where the engine only uses the cam sensor.

Are you running the original crank sensor at 200K miles?

I could look around my garage, I used to have a box full I bought off eBay some time ago. PC-17 odd that they are not a stock item any longer. . .

Just ordered Standard Motor Products PC17 on Amazon at $162.17. We'll see what happens.

Will do. Received conformation e-mail, no indication it was no longer available.
I put the same order in about 6 weeks ago, it said it could take 1 to 3 months to ship. Hope they have them somewhere.

That is some expensive little do-dad. I am missing how it could be priced like that.
If that is the price you have to pay to move away from a distributor, then give me a distributor !
I sure hope this situation changes. I am probably due for a few of these.
Our Suzuki has the cam sensor controlling the engine and the crank sensor (on the flywheel) doing the checking. When the crank sensor failed, it did nothing more than throw the engine light. That big flywheel diameter yields a lot more accuracy that the puny shutter wheel we have.
Help!

I have a like new crank sensor.

Has anyone approached the manufactures to make more? This shocks and scares me....having 3 SHO's.
Shosource is working to find a replacement
There is a good explanation of the DIS and the CPS operation in the SHO Engine Book. It is a hall effect device, which is the most common type. I don't have a SHO motor to experiment with fit, but it makes me wonder if another part number could be adapted. For example, in physical appearance, a SMP PC170 is similar. Harness swap would be easy if the mount and correct gap can be achieved, and voltages same. Just a thought.
Checked on this and it shows shipping in May, hopefully they come through
