ECM Module?

ECM Module?
I purchased an ECM Module from RockAuto for my 97 Ford F150. I followed the instructions to the letter. It was my understanding that if you used the numbers off of the old one you wouldn't have to have it programmed. The truck won't run. Mechanic said it has to be programmed. Who is correct me or the mechanic? Someone PLEASE help me out and answer this very important question.

You don't indicate what numbers that were matched.
There is a part number and a calibration number.
All part numbers are identical hardware wise.
The calibration code indicates the software version.
Part number and code needs to match.
I wouldn't put is past an online vendor to not get the software correct or to forget to install it.
More questions:
Why was ECM replaced?
Does the engine crank at all?
Have you checked the presence of the big three (fuel, air, fire) to see which is not available?
What was the calibration number?

I had good luck with an ECU from https://www.fs1inc.com/
I gave them my VIN number and they sent me an ECU programmed for my truck including all the recommended factory updates. My truck is a 2001 so I needed to reprogram PATS and sync the ECU with the rest of the modules.
I don't think 97 had PATS so you may not need to worry about that. But you might need to sync the modules. Free forscan software can do both the sync and PATS programming.

FJG is correct. No PATS in 97 - so it should not necessitate a programming to run. What was the reason for replacing it? What was in it before, and what did you purchase? Not enough info to help you much.

"PATS" or now what's called Securilock started in 99 for the F150. There were OEM anti-theft and alarms available though.

That I didn't know. I know they could disable the truck though. I've have come across differences between one that alarmed with the horn and one that had a siren and they effected the truck differently.
EDIT: Another oddity is with the early 99 4.2's like my Sept. 98 built truck. It used the type B Pats from the 6 cylinder Contours which had Pats before 99. There's is nothing in the manuals about this though. I found out through my VCM. It uses a stand alone module unlike the typical HEC Pats on the rest of the 99's.

No ECU,ECM or anything like that with these trucks....for the modulars anyway. They are all part of just one PCM...package deal. Flagship 1 had my replacement after I cooked my first one in the old 98.

It won't have any codes if its never run. Can you run the self test with your scanner?
