    SLK320 6 speed no start (possible immobilizer)

    All, I bought an 01 SLK320 with a light hit (airbag did not deploy). It's a manual car but does not want to start, even when the clutch pedal is depressed.
    I see some wiring from a fuse box going to the transmission down to the back of the engine (firewall) under the car and also to a cheap looking to a siren. I suspect that it's some sort of immobilizer. I'm wondering if it's wring to the starter or to maybe a neutral safety equivalent for a manual transmission car could have been.

    I won't be able to get the car in the air for a while due to space constraints but I'm wondering what could have been hacked if anything in order to prevent the car from starting.


    Any thoughts would be appreciated

    There is no any safety switch in transmision or clutch pedal. Check K40 relay.

    Is the wiring for an aftermarket alarm system? If so w/o the keyfob you would have to find the overide button (most cases in the glove compartment) and depress it and it will start.

    Just a shot in the dark.

    OK I got it running, that dodgy wiring was spliced into the factory wiring so I cut it away and bridge the wires together from the factory harness. I still need to make the rest of the alarm system disappear. Here's a quick video for anyone who's interested: https://www.youtube.com/watch?v=OW3-3tqNkX4
