Mercedes ml430 pumped brakes now no start

I have no start issue after turning key few times n pumping brakes.dont ask why i did...(hoped to get lights off) now sill not start also shiter doesnt lock in park when key out. Noticed ignition wouldnt lock until. Pulled battery cables put back on that part seems fine now with lock..brake pedal been noticeably softer can hear noise under me when press pedal when runnong recently...also b4 no start iissue pumping brakes when not running heard kind of click noise...have no fuel pressure whatsoever now and also put gas into filter starts runs rough...please help....does abs module/pump being bad create no start issue??
