95 cav wont start sometimes

my 95 cav at times will not start. kicks and sputters but wont stay running.sometimes wont start for days, then i will try it and it will start and act as if there was never aproblem. once its running all is fine. when it wont start, it acts like an old carbuerated car with choke problems. i have replaced the plugs and wires and idle control module so far. also keep dry gas in it and at times put fuel injector cleaner in it. thanks for any help.

First try pulling the trouble codes and see if the computer is seeing anything. Some parts stores will do this for free.
