BMW: bmw oxygen sensor, oxygen sensor, bmw 525i

Question
I installed an oxygen sensor in my 95 bmw 525i.It ran for a minute than quite and now it's like it's starved of fuel,it turns over but won;t fire. Any ideas. I had it jacked up on one side and I;m wondering if there is a shut off or rollover fuel protection switch somewhere that has to be reset.

Answer
There is no shut off rollover fuel protection switch on that car that I know of... And jacking it on one side wont cause that. It would be silly , then anytime u change a tire youd have to reset it. However it sounds like in the process you either didnt fully connect the O2 sensor (possibly forgot to plug the cable in) or you may possibly have a bad fuel pump.
