1997 SL 500 wont start

Hope someone can help.... 1997 SL500
I got the top windshield hydraulics (Top Hydraulics) re installed, top working great now, (rollball light still on dash and RB switch when down), changed oil, air filters, started and ran then vacuumed engine bay... now wont start....turns over but wont start, checked all fuses, not showing any codes with my reader, has gas and battery is fully charged, tried steering wheel tilt, transmission in and out of gear, brake on unlocked and locked from Drivers door and trunk ........fuel pump seems to be humming along does it bad that quick?
UPDATE-after battery reset, the car started right up, then I found out one of my keys had de programed, thats all it was

Just a guess, although no codes are being displayed.. but sounds like a Crank position Sensor.
