Default Help. Car bricked.

08 sti stage 3.
Driving around town, shifted from 3-4 at maybe 5500 rpms, heard a thunk and the car shut off.
All the blinky lights illuminated, temp gauge is pegged at highest level.
Car won't start- by that I mean the fuel pump doesn't prime, the starter doesn't click, nothing.
Oil is low but not empty, coolant is good, no smoke or smells.
Accessport won't connect to the car, says the key must be in on position- in every key position.


Ideas? I'm at a loss. Makes me think ignition went out, but that wouldn't explain temp reading.

Ok update:
Car was towed to my garage. The engine and fluids are all cool to the touch by now, but the temp gauge in the dash is still pegged at the highest reading. accessport still won't connect. No CEL but it is in limp mode. No sound of starter or fuel pump when I turn the key. Just nothing but blinky lights.

Pulled the battery cables and most of the fuses I could think of and didn't see anything wrong... This is so annoying.

I suspect the thermostat is bad, but it's a moot point right now.

It seems like all the items which are controlled by the sbf5 30a fuse are not working- ecu, fuel pump, ignition, and ecu connection, but that fuse is good and getting power. Maybe ecu ground is bad?

I've heard of the engine harness -> bulkhead harness clip in the engine bay coming loose due to hard driving (the big one mounted on the passenger side strut tower).

If you haven't connected a regular obdII reader, then it sounds like a bad ecu at this point.

The AP is an OBD2 scanner, but yeah certainly sounds like the ECU is either entirely off/unpowered, or dead. Would of course make sure it has power first.

At your data link connector. Check pins 6 & 14. (CAN HI LOW) Key on engine off. With a dvom of course. 6 to ground. 14 to ground. You should see 2.5 to 2.6v CAN HI. 2.4 CAN Low. If not, CAN Bus issue. Shorted to ground or open. Somewhere on High speed CAN (ECM, VDC) Coolant gauge is kind of a giveaway. From my understanding anyway. Lmk what you find. #subiegang

While you've got the DVOM out, head over under the glove box and make sure the main relay's 4 larger terminals are all B+ when key on engine off.

If they're powered up, pull the carpet and make sure the ECM is getting power in appropriate spots. I'm going to bed now, but I can look up the wires tomorrow.

Edit: What kind of thunk, how loud and where in the car was it?

Checked the obdii with dvom, with the key off pins 6 and 14 are not getting power. With they key ON, they are.

How would I trouble shoot the "can bus" issue?

I can't find the main relay, I must be missing something obvious, but I'm not seeing it under either side of the dash...

Kind of makes more sense to diag a can issue with a scope, but if those readings are normal at KOEO its probably not a can issue.

if you can get a pinout of the ECM I'd check power and grounds to it.

Either you blew a fuse, or the ground below the coolant expansion tank is loose. That is the ground that the ECU uses. If it isn't connected or if you blew the ECU fuse when you turn the key the cluster will black out and there will be no clicks.

You will not get any voltage from pins 6 & 14 with Key Off Engine OFF. What are your voltages that you got Key on engine off.

These are good suggestions. Start with the simple things like harness connectors before going all pinouts on it. I had a similar situation during a motor reinstall. Main harness connector at the firewall was almost plugged in all the way.

Did you ever figure this out? Sounds like a blown fuse. I had a similar issue recently and it ended up being a fuse under the steering wheel area that powers one of the slow blow fuses, which powers the main relay.
