Crank censor. But we need to know if they aren't firing first. Just hook up a multimeter to one of the injector connectors and crank it over. You should see your meter jump every so often.

If it was the crank sensor he wouldn't be getting spark. I would check the ignition control module.

Do you have a scan tool capable of reading P, B, and U codes?
Yes, it is not the crank sensor, because he has spark....
Have we established if we are getting injector pulse?
Do you have a tach in the cluster? Is it reading rpm'* while cranking?
