Check Engine Light 92 400E
Help.....have check engine light illuminated again on my 92 400E. I'm tired of dealer trips to interpret the fault. Does anyone know where I can obtain affordable diagnostic software that wont bust my 3 kids college education fund...(maybe they should go to community college instead....mmmm)...we'll see. Thanks

You might want to make yourself a pulse reader. A real impulse counter costs about $350, but you can make your own for about $20. Not only can you use it on the KE (fuel injection) system, but on the climate control and SRS systems. A must-have for anyone with a pre-1995 Mercedes (which of course has diagnostics).

I'll try to send you a scan of a schematic I made. It's easy and cheap to build because it uses a blinking LED instead of an LCD and counter IC to display the pulses. The only drawback to my version is that you have to count the pulses yourself.
