I just finished a rebuild of my 01 Cherokee Sport.
Started up ok then would not start again - crank position senor was bad (also was new) replaced crank sensor starts fine but when I put it in gear nothing happens - I also get nothing on my OBD II - blank screen
Any thoughts/ideas?

Check for blown fuses.

Thanks for the reply
All fuses checked out fine
Is there a relay or similar?
Also, why no reading from my code reader? I'll try it on another vehicle to make sure it is ok
