I run into a wall and totally puzzled the Benz it's a 1994 S420 with 85K miles it gives me a fault code 19 and 7 now the 7 don't show up any more all i get is the 19?
This is what I checked so far
Fuel pump working pressure good
Spark plugs good
Spark plug wires good
Wire harness good, it was changed
Distributor caps good, a note here (Before the removal and cleaning of the distributor cap I was able to start the engine and kept it running for 20 or so minutes now it won't start at all)
And last I check the the vacuum lines all hold pressure except one from the ICM (ignition control module) the rubber at the engine side was cracked replaced and still won't hold pressure.
Desperately need some help with this, thanks...
