Another 'theft' no start issue.
First time posting in this forum.
99 Navigator. Using info from this forum, I replaced a leaking heater core and reassembled dash. Refilled coolant and started to begin testing the
new heater core. Truck ran to fine. Shut it off to check for leaks near firewall, all looked well so tried to restart and got the theft light. Turned over but will not start with key or fob remote start.
I searched the forum and found many threads with this issue related to PATS system. Tried a couple tips without luck.
We have owned this truck a little more than 11 years. It has many modifications including remote start all by the PO. Never had any issues.
Question is why would it start once after the repair and then have the 'theft' warning with no start after.
I have a conector that I have not found where it belongs in the passenger footwell near the door that may be related but it did start on the first attempt.
Any help will be appreciated!

Its possible. I'll have a look! Would that cause the Theft warning I'm getting?
Seems that as a new member, I can't upload pictures quite yet. I uploaded a couple to my 'pictures' in my CP of the connector I can not find a home for in the passenger footwell. Not sure if others can see it? Could use help understanding where it belongs.

Verify the Check Engine light comes on during initial prove-out.
Put the cluster into HEC Dealer Test Mode (google it) and see if you have any PATS-related DTCs.

I'm pretty sure if pats system is the problem, the engine will not even turn over.
I have a non-programmed pats key for my expedition and when you try to use it the engine does not even turn over.
I'd say if your engine is turning over but not starting, it's most likely some thing else.

Thanks for your responses.
Checked fuses. All okay(visual check, did not use multi meter)
Check Engine light worked normal
Went through the HEC test and had no DCT codes
Also, I should update that the engine does not turn over anymore. Every function has been tested including lights, climate, suspension etc. All working normal.
Seems like I have a PATS/remote start issue due to dropping the steering column and stressing the aftermarket wiring. Worked great for 11 years before the heater core leaked.

The 99 Navigator was not equipped with a starter interrupt as part of the PATS system. The 97-98 Navis did have it as well as the 03-06 Navis and Expys.
The aftermarket system, who knows.

Thanks for the info! I need to learn more about the remote starter.
While going through the tests yesterday I noticed that the P RND21 indicator on the steering column was not quite in line and does not move when shifting. Stays close to the park position. Would the indicator be attatched to the neutral safety switch on the tranny?

No, the indicator has a fine wire running to the column under the dash. As you move the shifter it pulls on the wire and moves the indicator. It's all mechanical and has no electrical components to it.

The DTR switch, which contains the NSS function, is mounted directly on the transmission. Follow the shifter cable.
There is a fuse in the starter circuit. From memory, F21. Under the dash, also from memory (which ain't as good as it might have been).
