Test all your fuses with a test light. If the coil drivers aren't working you could have a fuse issue for the PCM.

How do you know there is a crank sensor signal getting to the PCM? Are there any trouble codes stored in the PCM? If so, what are the numbers? While your cranking the engine is the check engine light lit while the engine is cranking?
Usually if the PCM sees an rpm signal it will turn off the check engine light while the engine is cranking.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

first, thankyou for your time. yes check engine lite goes out when you crank enginge
after cranking a few seconds and not starting check engine lite comes back on and stays on. until you try to start again , no codes in the pcm. where can i get a print ,digrahm with locations of relays , modules and a print that works. the (typical) one which shows a coil pack instead of 6 coils like the sabel has. if I do'nt belong to a club to get one.

There is just too much information to put in here to show you where each and every component is including all the wiring schematics. You best bet would be to get a subscription to something like AlldataDIY. It's not really expensive and you get to keep the subscription for a whole year.
Was this running before you did your alternator replacement? Did it have any running issues prior? How did you damage the crank sensor harness? The starter isn't anywhere near the crank sensor.
Just out of curiosity unplug the engine coolant temperature sensor and see if the engine will start.
