I would triple check those connection points verifying they have good contacts and everything is back as it should be.

I caved and had it towed to the dealer by me. This was on Tuesday. Got a call Thursday that they've been working on it but still have no answers. Annoying but also makes me feel better that it wasn't just something stupid I did.

Hopefully mid week I'll have some answers. I'll update when I get them.

Thanks for all your help guys, it is much appreciated.

So I got a call from the dealer today. He said they were def scratching their heads with this one but ultimately they swapped a known good direct ignition coil out and sure enough it started to fire. I'm really surprised that all 4 of my coils which are less than a year old would suddenly be bad. It seems...odd. So, including diagnostic time I'm looking at around $1100 to replace all 4 coil packs with oem subaru ones plus 1 hour labor. I'm really.on the fence about this one and thinking of just buying new coils and replacing them in the lot lol. Would save me around half...if they're even right.

Thoughts?

ouch, if you can have them give you car back, just pay for the labor and diagnostics and find set of used coils for $100 and call it a day, if you can.
Or tell them you can bring some used coils for them to put in, I say that is allot of money, but its your call.
I never heard of all coils go bad all at once, even two coils could of started car up, even one would give you rough rough startup but will not run.
thats crazy

I wonder if something fried the old ones? but usually the ECU is the first thing to go in the event of a short circuit.

Jeez OP im sorry
Read entire thread thrice

Lots of good advice in 1st page
Assuming all that checked out,
I will hang my hat on AM alarm

If there is no OBD2 codes(assuming)
The 1st thing dealership will try is $1k of coil packs(understandable I guess)
Lots of people would next point to ECM
Maybe(as u described, no signal from ECU to injectors)
Possible, but some electrical blunder during installation of engine would of occurred
Like with me, trying to jumpstart car and swapping cables to wrong terminals kinda thing

Something is preventing throwing spark
If no CE lite pointing you/dealership in right direction, u might throw $$/parts at issue to no avail
IMO
It is a mechanical issue, like crushed pigtail pin/pinched harness kinda thing
Or that alarm

So I tried replacing the coils with new Delphi ones (warrantied the old ones). I paid for the diagnostic and got the key and spent 20min swapping out the coils for the new ones. STILL NO START.

I ended up handing them the keys back and authorizing them to order and replace the coils with OEM ones. Guess we'll see. I have my doubts tho and think it's either the alarm system (which I'm also not entirely sure of) or the ECU itself, which I'm leaning toward as the culprit at this point.

They said the parts won't be in till Wednesday and the next day the tech works is Friday. So, now I wait.

Dealer techs….damn. I have never met one who could work on a 10year old car. Has anyone ever ever seen 4 coil packs fry at once? Should be able to manually fore the coils, should be able to verify the trigger to each coil. Hell, I could even fix the transistors in the ecu if it did short something out. If the coils did cook, and I’d bet a good bit they did not, what ever did it is still lurking around. Dealer techs and transmission rebuilders, I don’t trust them.
