    Ok, we have a 1993 Mercedes 190E model, believe it is the 2.3 L. About
    3 months ago it quit while someone was driving it. So it was parked
    while we found time to work on it, we tried starting it one evening and
    it fired up fine, ran for five minutes and then quit. It has not
    started since, it does crank. We have done the following and are out of
    ideas:

    Changed the distributor cap
    New rotor button
    New coil
    New crank sensor

    The problem we have narrowed down to after all of this is that it is
    still not getting spark/fire to the plugs. I have tested to see if it
    has an alarm (by locking doors with window down, from outside with a
    key, reach in pulled the plunger and opened the door. Also tried just
    pulling the inside handle, neither time did the alarm go off if it has
    one), assuming it does we've been told this could be the problem. Thing
    is, we don't know where it is located or what to check on it. Also,
    assuming it doesn't have a security system, what else could be the
    cause? Please post any ideas, as we are near taking it to a mechanic
    and would rather not cough up all the $$$. Thanks!

    Fuses, replace all of them first, then see if the wiring harness is
    frayed by cutting some plastic by the injectors. They used
    biodegradable insulation from 89-93 because the US said they had to.
    Once they short your screwed about 600 new becuase you probably wont
    find a good one used. Once you try that email me.

    Does that mean they didn't use biodegradable wiring on euro models?

    As far as I know they used it on all model, they only had one place
    pumping out the wiring back then.

    Overload relay fuse... overload relay and fuel pump relay... all located
    behind your battery behind the black plastic cover.
