Please help. Lots of engine code errors.

Pull the driver's side fuel rail and swap the injectors. Then wait to see if you pop a P0204 code. Or, as a possible "I'm feeling lucky" move, replace that injector altogether. Worst case you'll have a known good spare injector for future troubleshooting.

If in either of those scenarios you keep getting P0202, then the problem lies in the connector or upstream.

There are other things you could do to test but it requires a multimeter and/or a 12V pwr supply to test or trigger the injector manually.

For reference, these are the codes that indicate a coil pack/igniter.

So if I still get the P0202 after swapping injectors, then we still think it's the coil pack? and if not it's the injector? I'll try that next. I've never taken apart an injector or fuel rail but there's a first time for everything. Just as long as I don't end up like Matt.

No, then it gets more complicated. Forget about the coil pack. I wasn't paying any attention to your codes when I first replied. Sorry about that.

Hopefully it's just the injector then. I'm guessing I'm doing the direct injector first to see if it's switching codes and the port injector or only direct?

Not the DI. Just port injector. Swap #2 and #4 port injectors and see if the trouble code follows the injector. If the injector is bad, you will see a P0204 code instead of P0202.

The direct injectors are the ones on top with the metal cover correct and port are on the bottom some where?

The port injectors, the ones you're interested in, fit into the intake manifold. It's pretty easy to get to them. The direct injectors fit right into the head.

I'm glad it's not the DI injectors as I'm watching this video currently and I'd have to take my supercharger off to get to them! [ame="https://www.youtube.com/watch?v=sdeO4rBwuQ4"]Scion FR-S BRZ Direct Injector Seal Replacement | Problems and Issues - YouTube[/ame]

I just found your other thread. I wasn't aware the ECU was able to detect coil pack failures. That's a first for me. Damn things keep getting smarter all the time

I'm going to swap the port injectors right now so hopefully all goes well and I don't break anything else.

Don't forget to bleed off the fuel pressure or catch it with a rag when you disconnect the fuel line from the rail. Easiest one to disconnect is the crossfeed line between the rails. That's the one with the blue clip.

That didn't go very well... I took out the fuel rail shield, the fuel rail, and swapped the injectors. I looked at both injectors and they seemed ok. I plugged it back in and one of the bolt holes stripped. I turned on the car and gas spewed everywhere. I pulled it off again and notice the injector that was in the 'bad' port has a washer that's bad (in multiple pieces). I'm not sure if I just didn't notice this before or not. So I at least have to get a new injector or rubber washer for it if they sell those separately. Not sure if it's ok to have only one bolt hole working properly. I can still tighten it, but when it's all the way on it just keeps spinning. The bolt is fine but the hole isn't. Damn car!

I checked all the fuses again even remotely related to the o2 heater fuse and they all looked ok.

Tomorrow morning I need to call the Subaru dealer to see if they have an injector or injector washer by riding my bicycle down there. Hopefully I can get the damn thing working! I think I'm f'ed with the bolt hole.

Heli coil time! I know exactly which bolts you are speaking of too, it scared me how tight the factory torque was on Matt's car.
