Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris and independent contractor that helps customers here.
You mentioned he programmed the key, did he do one key or 2 of them?
With the key on now, the theft light is flashing rapid?
Thanks for letting me assist you. I hope I met all your expectations.

What is the battery voltage?
Will it at least crank?
Are there any aftermarket electronics on the vehicle?
Do you have an auto or manual transaxle?
SPI or ZETEC engine?
Remove the starter relay from under the dash.
Check pin 3 is it power all the time, pin 1 power when trying to start?
Is pin 2 ground when trying to start?
With the key on, briefly jump a paper clip from 3 to 5, what happens?
Below is a chart file.
Is your relay laid out like this?
I hate it when Ford does that.
Okay pin 87a is not used, do not test it.
Pin 30 or 87 should be power all the time.
Pin 85 and pin 86, one should be power and one ground when trying to start.
Jump 30 to 87 with the key on.
Can you test it again?
The PCM is not ground pin 86, that is why it will not crank.
Yes, key on, briefly jump 30 to 87
No start though?
Do you have a diagnostic tool to see which PCM and PATS system code numbers are stored?
Let it crank to see if it will start, I am pretty sure it will not, but worth a shot.
See if your tool will communicate at the least and see if any modules are storing codes?
Unfortunately we have reached the end of what we can do without the appropriate scan tool. We have confirmed the PCm is not allowing the vehicle to crank and start. When you replace a PCM 2 keys have to be reprogrammed to the vehicle. This requires a 10 minute security access wait time, then once in, all prior keys have to be deleted from the module and 2 keys reprogrammed back to it.
As mentioned in my first response, I would stay in contact with you. I've noticed you have not rated the post. So I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.
