Thank you for your reply...Yes...please take a look later at the slk230...I have an slk230 that has been setting for a year...I have rebuilt everything on this car, replaced the ECU, SKREEm and the ignition system, but no crank...I have actually gone thru 3 ECU/s trying to reconcile the crank issue...I can bypass everything and make the fuel pump and the starter work but something has to control the firing and fuel mixture (ECU)....Thanks again...LP
