I am in the middle of replacing the cps in my 94 4.0.

My cps is the on with the window that you can see through.

I put the engine at TDC after having my finger pushed out of #1.

Then, I inserted the new cps with the end of the vane line up at the mark on the window (manual does not say to ensure it's still lined up perfect after it's pushed all the way down in the block).

Then, I turned the engine two revolutions and went to the 26 ATDC mark on my pulley.

Now, when I try to set the position of the new cps, the voltage from the blue/orange striped wire never changes from 12 to 0 when turning it.

Does the vane need to be line up on the mark after pushing it all the way down?

I'm trying to follow ducksheperds posts in this thread http://www.truckforum.org/threads/camshaft-sensor.12492/page-2

I got the cps installed and set correctly. My truck runs excellent just like before. If anyone needs help installing this type of cps message me.
 
I spiked mine eyeballing it, because my engine is a 92 but my computer and harness are 94.

I would probably have just pulled the intake, then spun the engine until the vane pointed at a fixed point, then reinstalled it so the vane pointed at the same spot.
