looking for K38 300sl
 

i have a 1991 300sl (built 11/90) that won't crank, starter will crank when jumped. neutral safety sw tested good, alldata says starter lockout relay k38 is behind the inst cluster up to 1/94, but not on my car? perhaps behind the center console/radio as in later models? anyone know if i even have one? i do have a factory alarm. is k38 the immobilizer relay? schematics have conflicting info. if no k38 i must have a bad ignition sw???

any ideas? info?

thanks

NO K38 relay until the 1993 USA model year!

Electrical portion of ignition switch is the MOST common problem!

thanks thanks for the help mb doc you were correct the ignition switch was the culprit.

replaced the switch and it works fine.
