Any ideas as to what this issue may be? My 2012 CLS63. Battery voltage good, even with jumper cables on just for a good measure test. The car will not start when I push the start button , but the clock spins like it's resetting, lights and radio turn on, even after turning radio off. Check terminal connection to battery is tight. I did get a check engine light the day before, fuel pressure too low, reset and it ran fine after.. Maybe. I'm guessing the connection to the fuel control may be an issue or the fuel controller itself. Thoughts? Just odd that it would spin my clock, geez. I do have a tune on my ECU, could it be an ecu problem? Wondering if anyone seen this issue and has a surefire answer.
