I have a 1998 grand Cherokee 4.0. Recently i have had an issue with it starting.It doesn't do it all the time but what happens is it will just crank and nothing then after it sits and i try it again it does start.It has happened twice today being the second time.after getting it started it wanted to stall any help would be great .Now the other issue i have is for some reason my temp gauge wont work when the jeep is running but when i shut it off the gauge will read the temp but as soon as i start it it will go back down .
