12.4 voltage at rest is at lower limit, the true test is to check voltage while cranking, 11 volts is usually the limit. Make sure the battery monitor system (BMS) is properly reset after any battery disconnection or removal, otherwise the system will not charge battery properly, these cars are sensitive to voltage and poor frame grounds under airbox, etc. You can google search all this issues. Go to a Big Box Auto Parts (autozone, Oreillys, Advance, etc.) and get a free fault code scan and report back. Are you having any drivability issues? hesitation, shudder, harsh shifting, rpm rise/slipping clutch. BTW things like mileage and service/fault history help us, help you.

 

Sorry for the delay - it quit on me during driving and we had to leave it till today. We did install a new battery and it started right up. We got it home, it wouldn’t start again. My dad rocked it and it started. We did the test and got these codes:

p1450
P286f
P0646
P1450
P0456
P0606

The problem in this recall is not the actually the purge valve; its failure is a symptom of a flaw in the PCM programming, which the Dealer will reflash as part of the recall.

Good Luck, Rod

 

This just happened to me. It was the TCM. It was covered under warranty, but it took 7 weeks for the TCM to get to Ford. Some people have had to wait up to 6 months. My advice is to call around to Ford dealers and see if any of them have one in stock.

 

Happened to me 4 times over the 10 years I owned my 2012. Hopefully they've worked out the bugs in the module.

 

I looked at your codes. The No-crank no-start is being caused by the TCM. That has a 10 year /150k mile warranty through ford. Parts are currently not available for months.
Your other codes are caused by a stuck open canister purge valve. Ask your dealer if recall 18S32 is still open on your car. If so, thats covered under warranty as well. If not, its a cheap fix.
Good luck!
