I have a 98 Plymouth breeze with around 158k miles on it. It ran fine up until about 2 weeks ago. I parked it over night with it running fine before shutting it off. Went out the next morning and it wouldn't start on its own. Starts somewhat fine with starting fluid and sometimes on it's own after cranking the motor a few times. When it does start it runs really rough for a few minutes. Hesitates when pressing the throttle both when cold and at operating temp. I have replaced o2 sensors and the crank sensor in the past week. Put a brand new fuel pump in last year. Ive checked the cam sensor and I'm getting proper voltage. Injectors are working fine as well. I can hear the fuel pump kicking in when starting so I know the pump is working. I've called garages and all I get is that I'd have to bring it in so they can look it over. Any suggestions on what it could be?

Another issue whether related or not, my tachometer also has stopped working a couple of months ago. I don't know if this could be related to the big issue or not.

You need to check the fuel pressure. Although the fuel pump is working that doesn't mean that it produces enough pressure for the engine to operate normally. Fuel pumps can very well run great one minute and once the car is cut off and then restarted a problem shows up.
Fuel pressure should be 49 psi with the engine OFF and ignition switch ON.

If there isn't proper pressure could it be something other than the pump itself? My fuel lines are a little rusty and I have been told that the fuel rack could be partially plugged up too. I just want to get all the facts before I start digging into the car. That way I can check all possibilities at once.

A clogged fuel filter could cause low fuel pressure as could a faulty fuel pressure regulator.
You'll have to remove the fuel filter to check it by seeing if you can easily blow through it.
To test the pressure regulator, you'll have to have fuel pressure gauge connected to the fuel system and with the engine running note the fuel pressure; then disconnect the vacuum hose going to the fuel pressure regulator. The fuel pressure should increase it the regulator is working properly.
