'90 Cherokee starting problem

On some mornings, the engine cranks like normal but does not start. If I use starter fluid in the throttle body it will eventually start and re-start throughout the day. I had the crank sensor replaced six months ago after having the same problem. Could that sensor go bad again? The problem comes and goes, always originating in the morning. I would appreciate any suggestions.

next time it wont start try unplugging the tdc aka cps sensor if it starts up thats the problem and need to replace it... if that doesnt fix it then try pulling of the throttle body and cleaning it real good make sure and take off all the sensors first but be careful your throttle position sensor has to be adj with a volt meter when you put it back i dont have to do this they did away with that in 91....also try replacing your idle air control motor....
