Replaced Cats Now Check Engine Light Does Not Come On And No Start

[tommy33`]

Title says it all.
I replaced both cats on my 97 Discovery SE 7, 137000 miles.
After I replaced the drivers side, I started the car and it ran fine.
Replaced the passenger side cat and when I turned the key to the II position the dash lights came on except for the Check Engine light. I plugged in my code reader and it said "link failure".

Starter cranks but no start.

Changed the crank position sensor still no start.
Check fuses, immobilizer switch, wires to the starter, fuel pump. All seem to be OK.

HELLLLLLLLLLP!!!!!and thanks

I thought I replied to this... I am so sorry....

sounds like you may have loosened a wire set going to the ECU.... check that first.
