  1. B and I moved most of the rest of my business inventory to my machine shop across town. We took one trip with his Forester and my white Outback loaded with parts. Then while he was working on his car I loaded the white Outback up with another literal ton of parts. Almost as soon as we started driving the transmission acted like it was slipping. Got to the shop and unloaded everything, still slipping on the way back and has been ever since. I tried adding some brake fluid since my brother knows some people who've had temporary success with it but it didn't really seem to help. Plan to get a lower mileage replacement trans from a junkyard and hopefully a tan leather driver's seat while I'm at it. The Impreza has been taking a while to start fairly often since the swap after it sits overnight or longer. Sometimes it takes two or three tries before it starts. A while back I discovered this was because the crank position sensor wasn't generating enough voltage while cranking. Voltage signal on the Haltech oscilloscope looked decent but it wasn't enough. I lowered the threshold voltage and also added a column for 0RPM which seemed to help but still wasn't a complete fix. Then it just wouldn't start, was giving crank position and throttle body codes. I took apart the engine harness connector as that's been the source of most of my problems and the wire pulled out of the pin for the crank position sensor. I repinned that and checked the throttle body connections and it started and no longer had those errors but it was running rough, probably on five cylinders. I decided I'd had enough and ordered some closed barrel pin connectors and a tool from JR Ready. I'm not a huge fan as they're made in China and I don't like how closed barrel pins don't crimp on the insulation but M says they're the best thing they've found for wiring airplanes so I figure it might be good enough for trail riding in a Subaru. The week before we left I rewired the engine harness plug on the Impreza with some help from B. Shortened up the wires with a couple feet of excess length in the process. Directly wired the throttle body and MAP sensors to the ECU as they're pretty easy to unplug and then I'd have one less connection in line and fewer things to run through the connectors I added. Added four Deutsch connectors with closed barrel pins. I did zip tie them away from that bracket after I took that picture. Labeled and checked wires, pinned out the connectors, double checked wire color matches and tried to start the car Thursday. Only cranked but didn't fire. I checked various things, sensors seemed to be reading except the cam and crank position sensors. Then I realized I hadn't plugged that connector in. Then it fired up. Overall pretty happy with how that turned out, should be much easier to repin those connectors and the reduced wiring under the dash makes it cleaner and allows the glovebox to fit better. Bit of a last minute fix finishing that the day before we left but I'm glad I did it.
