Starting and stalling issues

I have a 95 4.3 v6 blazer and I have put a new fuel pump new plug wires and plugs rotary button and cap and crank position sensor fuel filter and I don’t know what else to do. I have problems starting it at first but I have to use a little gas in the intake just to get it to initially to start after that it runs with no problems. It will take off and shifts fine but you can only push the gas petal down 1/4 of the way because if you push it more than that it just Boggs down. Pulling wise it seems fine but you just can’t push the throttle down more than 1/4 of the way. It will even get up to 65 and 70 mph with throttle at 1/4 of the way down but as soon as you try to give it more throttle it sounds like it’s flooding or not getting enough gas. I push the bleed off valve on the fuel rail and it seems to have enough fuel pressure I’m going to check it as soon as I get off of work but I’m trying to figure out what the deal is with this thing before I go and spen more money on a tps and a cam sensor and air idl control valve. It gets very expensive when messing with these sensors

    Check fuel pressure.
    Pull the vacuum hose on the fuel pressure regulator and see if it is wet with fuel.
    If it is, then the diaphragm is shot.
    Check engine light on?
