I'm having the crank with no start prob I replaced cps ,alt,& batt & no success

What is your question?

First started I live in Philadelphia ,and we had a very , very bad rain storm all was well until I went to use the defroster's , than I get a red light on the cluster saying Alt/Bat so I corrected that issue by installing everything new !!! I drove for a few days the car drove great !! Until we came up to a red light , that's where it all went down hill ! The check eng light appeared and when it turnt green the car had no power !! It was stuck in limp mode ! I had the petal pushed all the way & the car wouldn't move luckily we made it to a safe parking lot !! This happened tues and the car hasn't ran since only on 2 different flatbeds towing me !!! I replaced the crank position sensor not just once I removed it & the company took it back as a default and gave me a new bosh unit which left me walking again !!! Can somebody please help me figure this issue out ??? My wife is driving me crazy!!!!
