2007 S600 Misfiring

Problem is that cylinders 1-6 are misfiring, no spark at all. I replaced the ignition voltage regulator/converter and still has the same problem. This happens immediately once I start the vehicle. Has anybody had experience with similar misfiring?

I think it could be your coilpack!

I ordered a new coil pack from the dealer($1500) and hoping this will work. If it's not the voltage converter or the coil pack what else could it be? I have no other ideas as to what the problem is

I am assuming you checked that you are getting voltage and that it is not a bad cable? Good luck! and let us know how you make out.
