Hello everyone I have a problem with my 1985 190e 2.3
the car has been running fine for a year.
suddenly when i let my sister use it things changed.
she went to start it and it's dead
all the other electrical things are working
but when i try to turn it over it does nothing.
i turned on the headlights and tried to start it and there was no power decrease in the lights. it seems to be no power going to the starter or possibly the ignition coil.the starter has worked fine with no signs of trouble
one other thing do the 190e 85 have a diagnostic system?
