Now the theft lite on the dash blinks and I can turn the starter over it will not start HELP! And yes I do have a small switch at the bottom of my dash but pushing the button does not help....can u help me. Thank You!

Answer
It's not the KARR system keeping you
from starting the engine according to this
explaination

When you replaced the ignition, the Ford PATS
system (passive anti-theft system) was disconnected.
This shuts down the fuel injectords.

It MUST be repaired. I can't help here as this is
is not something I can do or explain.

Contact the service department at Ford to
go from here on the info you will need.

Sorry bout that. Not all the news is
what we want to hear.

Good luck.
