    East Oregon. Reached out to ott tuner. mentioned in comments above. No one closer who has any experience, say Seattle. 275 miles away. No one will touch it.

    4 run, 2 don't
    Oof must've missed it, lots of posts.

    Was following for a bit and was shocked you're running boost without a tune, then saw you're running a piggyback.

    All wiring checks out, outside of the cabin? As in nothing shorted possibly after physical install of the supercharger in the engine bay?

    Someone did mention to check all grounds if you still have a no-start.

    I have a test light. I dont know how/ where to check the grounds. My plan is to resplice the wiring with better solder procedure. Check exhaust cam sensor on head/ replace.

    I would say you need to focus on figuring out why you are having that issue with that cam control circuit.

    Might be as simple as a loose connector. Give that is is the B cam, I am going to guess that is the exhaust cam and I think that one is in the cam cover its self

    This is from the tech support @ urd. Some proper splicing, and rewiring. Recharging the battery. Testing and replacing that thing on the cam was my plan, here soon

    P0010 (intake) is similar to P0013

    These 2 throttle position related could be a byproduct of your Camshaft code. But you need to check the wiring on 2 pins: 30 and 18

    Probably start checking every sensor wire on ECU pins.

    Where those wires/pins are part of that black tape bundle in the photo you posted a few days ago?
    So far it seems there is a signal loss from sensor to ECU and there is a voltage difference for throttle position sensor(check failure) perhaps due to bad splicing.
    You have a diagram for sensors pins.
    Check wiring, repair if damaged, clear codes, crank the engine. You may run a wire directly to sensor to eliminatethe harness. May need to get a tiny probs to get to the pins on sensor connector.

    Seek for OBDII tools with active functions to test various sensors, etc. I would get a techstream app at this point.

    I would still pull spark plugs out and manual turn the engine to check for compression /vacuum.

    Toyota app may give you a specific code for throttle position sensor code vs generic you get from that reader

    what does suspicious solders look like? ive done a few soldering on electric guitars and on my radio install but if you made full contact and then liquid flux + solder + heat shirnk i would feel confident that everything is correct.

    For wires:
    • Cold joints (i.e. moved when solidifying)
    • Overheated/cooked solder
    • Not enough solder/poor wetting (even if wires touch, it may not make good connection)
    • Too much solder (prevents good inspection, should be able to see twists in wires, if stranded)
    • Flux left behind (if the corrosive type)

    Now, don't think I'm saying this to scare anyone, it's really not as scary as it seems.
