4 cylinder, 2.5.. turns over good, normally starts right up pretty good. now since we've done this it won't start. no spark. what could i have knocked off to cause this to happen. also this is the 3rd slave cylinder I've went through. i've had this truck 3 years. and all 3 have happened this year. any idea why i keep going through them.
If your buying cheap parts you will have this problem.
Can't help you with what you might have knocked or damaged while replacing the slave cylinder.
A slave cylinder is an uncomplicated piece of kit that usually gives good service for many years and few things shorten that life. One of these is using fluid that is incompatible with the seal, another is overtravelling and a third is corrosion.
When the first replacement failed it would be usual to dismantle the failed cylinder to discover the cause of failure, which with only (usually) a single seal to examine would be fairly obvious and might or might not be a reason for a warranty claim.

I'm certain that there is an "official" test for this sensor. I generally quick check by attaching a volt meter set to millivolts to the sensor leads and check for a pulse voltage when cranking. If in doubt and you don't want to spend big$ on the part, you can get an entire distributor at a scrap yard likely for half of the price of the new sensor.

Pull the plugs and compare them to the pictures in repair manual, ie: Chilton's or Hayne's. May be a bad injector flooding them or an intake leak causing a lean condition.

It sounds like your new crank sensor is defective. It should be under warranty.
