SLK 230 engine not cranking
 

First off. Thanks for having me as a member of the forum. I've read so many times and appreciate the network that has been established.

Vehicle:2003 SLK 230 Kompressor with 11k miles on it, I been owning this car for the past 3 years.

Today I go to start and although all dashlights (and radio) came on, no ignition. No cranking/kicking. I try a few other times, same thing. Went through standard battery checks and recharge, still the same thing. I definitely believe thatthe battery is in good shape. I had that problem couple weeks ago. All the light in the dash board was normal. I wait around a bit then it started when I turn the ignition key.Can't figure out why there is no cranking.

The same happened a few weeks ago I wentto a store and when I tried to crank the carnothing happened, after 30 minutes or so of trying finally the car started up but when I came home it started doing the same thing.

Waited a few hours and start working fine. The same day I started checking with my 12v tester and when I check one cable that connects to the computer I heard a small sound (like a circuit activating) and tried to start the car and it works.

It kept happening and every time when I touch the same cable with the tester it started working, I guess is like if I were making ground or something. I thought it could be something related when the car is inpark but I guess is not that.

Just so you know battery was replaced a few month ago due to the same situation.

All the help I can get will be greatly appreciated.

Thanks in advance guys.

I HAVE REPLACED ABOUT A DOZEN IGNITION SWITCHES ON THESE FOR THIS REASON AND FAILURE OF THE STEERING LOCK TO DISENGAGE. i CAN'T GUARANTEE IT BUT I'D CHECK IT FIRST. USUALLY RECOMMEND IGNITION SWITCH WITH STEERING LOCK TOGETHER TO PLAY IT SAFE.

Starter or it could be you transmission shifter module...i need to hook it up on my sds (star diagnosis), and check out actual values!
