I was jump starting my car, and accidently connected the jumper cables backwards to the car. Now the car woun't start it cranks over, but as soon as it starts it dies.

Start by checking all fuses and pray that you haven't blown a control module.....

Guaranteed ECU blown. Most prolly the top control ECU too.

You can get them checked out/repaired at Beckmann Technologies.
If you call them on Monday...talk to Robert and tell him what you did...take his advice.

Ok checked th fuses they all are good. Next question is where is the top ecu

Usually in the trunk above the battery.
...or ask Beckmann.

"Guaranteed ECU blown. Most prolly the top control ECU too" ????

"Usually in the trunk above the battery" ?????

what the truck are you talking about??

The engine control unit is located in the relay/ fuse box next to the battery.

the battery is under the hood, not in the trunk

Sorry.. .the last SLK I worked on, battery was in trunk next to right wheel well in a battery well...my customer had shorted the + to the body and fritzed the 'top controller'......and top control module was against the 'B' pillar, right side, above the battery.

We are talking about a Mercedes , yes ?
