Ignorance on parade!!

I like puzzles but...
I picked up a 2001 Sport before I realized all the electronic compatibility issues.
The kid I got it from had swapped engines and swapped the auto for a standard.
Now, of course, it wont even start.
I've had suggestions like "trace all the modules" or get a whole new wiring harness made (big bucks).
Does anyone have any ideas about how to solve this puzzle without spending way more than the car is worth?
Thanks

Swapped which engine to which engine? Left the original ECM in? Used the new engine harness or spliced into the old or no wiring done? Did it ever run after he swapped the engine?

Do you have the old engine? What did you pay? A non-running frankensteined '01 is probably only worth scrap value so it's not looking good. Only other thing is if he swapped the ECM from the other vehicle, it'll either need the key and steering column lock cylinder from it too, or be reprogrammed for the key to the old ECM which is something that a dealer or a > $1000 tool is needed for.

If you have two of the keys for the new ECM, in theory you might be able to hold them up to the lock cylinder while the new key (meaning original key that fits the lock) is in it, to get their ID read and program a new key using the owner method, but you must have two of the keys already programmed into the ECM present to do so, to add a 3rd key.

if you get lucky you could try the failsafe programming mode, it doesn't work on all ford ecms. put key in, turn ignition to run , let it sit fifteen minutes, it -might- program transponder code into system. some firmware revisions on the ecms do not disable the blank ecm fail safe key programming code after it has transponder codes stored.

failing that you may need someone with the ford or aftermarket tool (like i have) to clear the old transponder codes out of the ecm and program your transponders in. that is going to take 15 mins to blank and another 15 mins to code in the transponders from your keys, it can't be done in one step, you have to reset the ecm/computer between the steps. if you were in western wa i could probably do that for you.

look under the steering wheel for a push-button, you might have a factory or aftermarket security system, the button is the valet override and should allow a key with an unknown transponder start it. basically the button energizes the starter relay which the PATS system and factory sec or aftermarket sec system DE-energize)
