1989 Oldsmobile 88 won't hardly start shutters with acceler

Ok well as I said won't hardly start and when it does run it just shutters. Poor idle. I was driving on night and I felt a hick-up and the next morning it was worse. By that evening it was almost undriveable. I put on a new fuel filter air cleaner plugs wires and coils. I have recently replaced the water pump. I have checked the fuel presure(not with a gauge I don't have on) but when I press the valve fuel sprayes out all over. Ever time I've had bad fuel pressure in a car it was nothing like this. This really sprays out hard. In my non professional opinion the fuel pressure seems good. I ran the paperclip diagnostics and came back mass air flow sensor, code 34 I changed that and reset the computer and still no dice. It requires a small shot of ether to start and then runs like the timing is bad or the module is bad. But I had the module tested and it came back as good. I've checked for vacuum leaks visually and listened with my ear but I see and hear nothing. I have also tried spraying a little ether around the intake and vacuum hoses. And I got no change in the engine idle. I'm pullin my hair out! I ve had people say it's the knock sensor or still a bad fuel pump but I can't keep throwing money at guesses
