Did your XJ come with a factory alarm. If so put the key in passide door lock and turn three times. Left right left right left right. I put a motor in my 91 and same thing. Took a week for me to figure out that it had a factory alarm. Once you clear the alarm she fire right up DOH!!!

Well, the basics first. Make sure you connected all of the sensors including the CPS (on the bell housing). Double check all electrical and vacuum connections.

You can see how to test the various sensors here:

The CPS is on the upper driver's side. There is a connector near the coolant temp sensor (which is on the driver's side, rear cylinder head).
