My KK is giving me fits at the moment. I have 2 seemingly unrelated problems at the moment, but maybe they could be related. Hopefully somebody knows.
I've been having warm start issues. Sounds like the trucks flooded. I turn the key and it cranks but won't fire up (i've made other posts about this). After a few tries and pressing the accelerator to the floor the engine will come to life. I'm assuming at this point that is a leaky fuel injector. This problem needs to be dealt with but as of Thursday the jeep started to overheat in traffic (climbed to 3/4). Now I had this issue a few months ago and I replaced the radiator and the water pump and that seemed to fix the issue. Fast forward to now and it's happening again. I got it up to temperature and I looked under the hood and noticed that the radiator fan wasn't working. I cranked the AC and still nothing. So, I thought I should replace the fan, so I did that yesterday. Went to drive it today and the temp gauge wasn't moving and I got the little electric bolt with 2 lines CEL light, so I thought I hadn't plugged something back up, so I pulled over and cut the car off. I cranked it again and that light went away and my temp gauge was back to life sitting at 1/2. I drove for a minute longer and found a parking lot and the darn temperature started climbing again! I'm at my wit's end with this thing. The only thing I can think of would be the coolant temperature sensor. I think it's been known to spark the lightning bolt CEL and would explain my temperature issues, right?
Does anybody have any other ideas? Bonus if you can tell me if this might be causing my hard starts.
