PATS madness/electrical mystery Please help!

![Default](/forum/images/icons/icon1.gif)
Hello friends,
I have a pre-facelift 2002 4.0 S-type, (basically a 2001).
One day it would crank but not start, and the red PATS light on the dash was blinking a Code 16. This indicates a communication problem with the ECU and Powertrain Control Module. I read online for advice and I checked all fuses and relays. I discovered that PCM relay #2 in the box under the hood was bad. I got a replacement and the car cranked for about 5 seconds and then started! WooHoo! I drove it around for an hour, came home, parked it and tried to start it again 2 hours later......same problem was back....stuck in anti-theft blinking PATS Code 16, cranking with no start.
I have 3 keys, 2 regular and one valet, I have tried them all.
For anyone who has electrical knowledge, why would the new relay let it start once and but not again?
The closest Jaguar Dealer is 3 hours away.....that is a big tow bill....
Help me jaguar forums.....you're my only hope

Hi SchickER, try this:
https://www.jaguarforums.com/forum/s...s-sytem-34107/
The whole thread maybe useful too as it mentions anti tampering and I wonder if it is a simple case of reprogramming the key to the ECU or resetting the ECU?
Worst case scenario is I believe to be the recoding of the ECU by a Jaguar dealer, have you checked fuse #6 or ~18?
Good luck! Stu
