    Yes, I did try to start it with the switch enabled to test it; kill switch functions as it should. I haven't pulled any codes yet or driven the truck to see if operability if effected.

    Per their trouble shooting FAQ:

    ISSUE:
    Because the Kill Switch (when activated) prevents power from reaching your vehicle’s Starter Motor (or Fuel Pump motor); your vehicle’s computer may incorrectly interpret this as a problem with your Starter Motor.

    SOLUTION A:
    Remember to disable the Kill Switch before attempting to start your vehicle–so that the computer never sees the Starter Motor as having an issue.

    If you do accidentally try to start your engine with the Kill Switch activated (and the check light comes on); you may have to cycle your vehicle a couple times (i.e. shut off engine, restart again) to clear the error code (check engine light).


    I cycled the engine a few times and no change. Hoping simply disconnecting the battery for a bit does the trick. Otherwise, Ill pop the OE starter relay back in and reach out to the vendor for support or a refund.

    Ya, you will do this more than once, trust me:)

    I installed a simple setup on my OBD1 Civic by creating an open loop to EFI fuse under fuse box. I regulary forget to hit the switch but no check engine light.

    He's just putting regular gas station gas in it. It's his truck but I'm tired of the moping so I'm being proactive. It has only been driven little short trips but they total up to about 20-ish miles. No oil seeping haven't noticed a reduction in power. Thinking maybe a leak in the air lines somewhere?

    Mines doing the same, I tryed starting with the kill switch on. I will disconnect the battery to solve the problem as well. It's just happened today and has been driving fine. I still love the kill switch, 2 of my co-workers got their trucks stolen last month.
