how can you start a '89 mercury cougar with a broken ignition switch?
it could be the coil pick up in your distributor
Where is the start located on a 1986 420 Sel Mercedes? My car just cut off with no warning. I tried the ignition switch and engine will not not turn over. All other instruments are working when the ingition is engage.
Check the fuel pump or the fuel ignition if its not getting gas.
I can't say for certain but I think that year has a crank sensor which could be bad also it could be a fuel problem or even an ignition problem
More than likely it is your ignition module on the distributer. if not its the coil.
It can cause the ignition lock cylinder to not turn. If it turns then the key is not why it will not start. Look into the ignition switch, starter, battery, or connections.
Turn the AC or the Defroster off.
It could be ignition module.
where to find electrical diagrams for starting system on mercedes 300sel 1989
Generally the problem is either a defective neutral safety switch or a bad ignition switch (not ignition key lock).
