Is it possible to bypass the CPS (Crankshaft Position Sensor, Crankcase Position Sensor)

I checked for previous topics on this but I did not find one about
bypassing the CPS. I am selling my 88 Comanche and wouldn't you know
the damned thing will only start cold, one time and thats it. My
experience with my 87 tells me its the CPS. I would love to just
bypass the thing so I can sell it, or at least so I can tell the guy
buying it that this is what the problem is. He is a friend of mine and
I am giving him a deal but he is not mechanically inclined so I will
end up fixing it for him anyway but I would like to wait for spring
when its a little warmer than 10 degrees outside.

By the way I am new to the group! My name is Erich I live in the
Rockies and I have had a number of Jeeps over the past 25 years. My
wife just bought me a 2006 Unlimited so I am learning all about Jeeps
again.

Thanks!

The CPS is how the computer knows how many RPMs the engine is making and
when the crank passes TDC (or some other benchmark), and syncs spark and
fuel (for FI) to it. With no CPS the computer doesn't know that the
engine is turning at all.

No problem.
You will need a telegraph key, a rubber band, a surplus US Navy URM-43a
signal generator, a deer antler and an pineapple.
Tie the antler to the torsion dampener with the rubber band and some Elmer's
glue. Place the telegraph key where the antler will tap it on each
revolution. Wire the telegraph key to the signal generator set for 5500 Hz
at 4.2V and then shove the pineapple up your ass for trying to hide a
problem rather than fix it when selling a vehicle.
