Let me start by say'n I think the immobilizer may not be the issue.
start with a new key, this takes the old key out of the equation, it prolly will not work after, fallow the instructions intently.
Let me ask here, does the fuel pump prime with the old key?

The immobilizer is what got broken as it was running fine before that. The fuel pump primes with all the keys.

Once you get this fixed and it's been long enough to chuckle about it, you should name the car, "The Immobilizer".

Funny thing is I haven’t named it yet. Here’s some pics from when I first got it.

Different immobilizer than what came in the car you need you need to use a new, unprogramed key.

Are you sure you don't have a different issue?
Tried starting fluid?
Can you post a vid of what the 'anti-theft' light does when you turn the original key to the on position?

Theft light flashes rapidly for about 30 seconds then stops.

Update: finally got my sct Livewire tuner connected to the mustang. Uploaded a preloaded tune just to test it before buying a email tune. Now the tuner and my obd2 scanner are getting power from the obd2 but no communication from it. Any ideas? Fuses are all good. At this point should I just buy a 96 crown Vic ECM for it since they don’t have PATS and just lose my keyless entry?

Have you put a scanner on it to read codes?

Yes it gets power but no communication. Just like the tuner.

Bad ECU would be my guess.

It was working prior to me uploading the preloaded tune from the sct tuner so I’m wondering if it’s just hung up now or something else happened during the upload of the tune. Has anyone ever heard of or trying to bypass the PATS by installing a vics ecm? Seen it in some YouTube videos and a forum somewhere.

Are they the same ECU except no PATS?

Not sure exactly. Just seen videos of people changing the ecm in the 96 mustang with a 96-97 Vic’s since they had the same engine and other interchangeable parts I’m guessing. The model of the ecm I’ve seen used from the Vic’s is the ml2-333a

Interesting, was just thinking if the Crown Vics ECU would be looking for signals from sensors the mustang doesn't have, or vice versa. I don't know anything about swapping ECUs.

I wonder if the ECU Exchange folks can answer the questions about PATS and other ECU?

Me either lol that’s why I’m hoping someone can give me insight on it. I heard switching them out to bypass pats will disable my alarm system and my key fob but that’s all I know of.
