I have a 2016 Ford Fusion with a 2.5L engine and it just won’t start. It cranks but won’t fire up. I’ve looked into the fuel pump, battery, alternator, mass air flow sensor, and even added more gas just in case. I replaced the spark plugs and ignition coils three weeks ago. There’s no check engine light on and I’m stumped on what else to check. The ECM failed at the end of July and all the shops I talked to said it needed to go to a dealer since they had to get the parts from Ford and program it there. I took it to the local Ford dealership and they swapped out the ECM. I got my car back three weeks ago and it has been working fine since then. Could it be that the ECM they gave me is faulty? I’m reluctant to take it back because it took them several months to fix it last time.
If anyone has any other suggestions for me to try before going back to them, I would really appreciate it. I checked for OBDII codes and didn’t find any.
Edit: Just to clarify, I lost all power while driving on the interstate and the engine shut off. Since then I’ve been able to start it briefly twice before it shuts off again. The last time it started was yesterday morning and it hasn’t started since then, I’ve tried about 8 or 9 times.

Have you checked your fuses under the hood
Oh I forgot to say, I already checked all the fuses and everything looks good. Do you think I should try replacing the ones that might cause this issue even if they look fine?

I would definitely take a look at the ignition fuse. Not that I’m sure that’s the issue but I’ve had some blow after doing work when a wire shorted out. Sometimes the wiring harness isn’t secured properly and wires can rub against something. Good luck
@Olen
Thanks, I’ll check that next. But would it still crank if the ignition fuse was blown? Anyway, I’ll look into it, I want to rule everything out before returning to the dealer. I really can’t be without a car for three months again. Thank you!
@Reese
Sorry, I meant to say check your ignition coil fuse and also take a look at the PCM fuses. If they are blown you can usually tell just from looking at them but you’ll need to pull them out to see the sides clearly. When I need to crank a car that won’t start, I usually pull the ignition coil fuse or fuel pump fuse.
I had something similar happen after cleaning my car. It took three days to get everything sorted out. I used a jump pack to start it but it kept dying after driving.
I only drive for about 15 minutes at a time so I made longer trips to see if it helped.
Eventually, after a freeze, it stopped completely and wouldn’t start. I used a 1 amp trickle charger for eight hours and it has been running without battery problems for a year now.
By the way, it’s a 2014 Ford Fusion Energi, not a plug-in hybrid.
