Tell him you got a P0PITA -- incompatible driver or driver effectiveness below thresholdMy friend picked up the car, and the CEL came on as he drove home.
If it turns out to be a P0302 again, I'll pull the ECM and investigate further.

I'm sure he's a good driver. I likely didn't push it hard enough when test-driving it.Tell him you got a P0PITA -- incompatible driver or driver effectiveness below threshold
It wasn't broken so you decided to fix it?Back on the Fusion. There was no CEL when my friend brought it back, but I pulled the ECM and we took it to a local rebuilder.
It was running poorly. The CEL came on, but was off by the time I saw the car again.It wasn't broken so you decided to fix it?
With no codes, I would have left it alone
Also if the front three are OEM and you believe them to work, that's a known quantity and I'd move them to the rear.It was running poorly. The CEL came on, but was off by the time I saw the car again.
(I say poorly, but running like champ compared to now.).
I now wonder if we could have left the ECM alone - perhaps the cheapy coils were breaking down under load. Arg!
I don't know why I didn't previously check the front three coils for manufacturer, but they're also Spectra.Also if the front three are OEM and you believe them to work, that's a known quantity and I'd move them to the rear.
Even if the owner has used OEM on the shelf, I'd wonder why they were removed from the rear bank?
Or are the mounting tabs mirrored and they can't swap?
I didn't know Spectra made ignition components-- that's terrifying. I barely trust them to build a radiator and will not use their fuel pumps.
Man I'm curious, too!!@bdcardinal, I appeal to your knowledge of Ford parts once again.
So, I put things back together with three original FoMoCo coils on the rear bank.
The cars runs terribly, as before, and the same two codes come up - P0353 (bad coil CCT on #3), and P050B (cold-start ignition timing issue).
But anyway, I've now jumped through the ECM repairer's hoop, and have removed the ECM for him to take another shot at repairing.
I noticed that the original ECM and the donor have ve different part numbers. I wonder if this could be part of the problem ...

Your thoughts? And thank you!
His Fusion is a 2007 - still OK?Based on the engineering number you provided, these are acceptable replacement engineering numbers: The 7E5Z-12A650-AMARM is the service part number that would be on the box label. The other 8E5A PCM engineering number shows fitting 2008 and 2009 Fusion and friends 3.0L

If it ain't on that list-- which is furnished directly by Ford -- I'd tell the PCM rebuild guy to sit and spin.Based on the engineering number you provided, these are acceptable replacement engineering numbers: The 7E5Z-12A650-AMARM is the service part number that would be on the box label.

Agreed - all thoughts I've had. But I don't know what parts the rebuilder transferred over.If it ain't on that list-- which is furnished directly by Ford -- I'd tell the PCM rebuild guy to sit and spin.
When you're dealing with suspected "brain box" issues, why introduce an additional variable?
How will you ever know if future driveability issues are a result of an internal PCM fault, or just the incorrect PCM altogether?
Yeah, but unless you transfer basically everything-- including the primary circuit board -- it seems irrelevant.Agreed - all thoughts I've had. But I don't know what parts the rebuilder transferred over.
We'll give him another shot at it.
There are a number of rebuilders in the States who will provide a known good (tested and repaired as required) ECM, reflashed by FORscan to be compatible with your vehicle. (You provide the VIN.)Yeah, but unless you transfer basically everything-- including the primary circuit board -- it seems irrelevant.
If attempt #2 fails I'd start searching ebay and junkyards for the list @bdcardinal provided you. Now at least you have a fighting chance with that list in-hand.
I was going to suggest looking at who Eric O (South Main Auto) goes to to have electronics rebuilt.There are a number of rebuilders in the States who will provide a known good (tested and repaired as required) ECM, reflashed by FORscan to be compatible with your vehicle. (You provide the VIN.)
Depending on how things go here, that might be the way to go.
