It's an aftermarket electric fan, mine was originally belt driven

I have it set to come on at 215 (I think) and the temperature was always slightly over the center notch on my gauge, sometimes further right with all the uphills, sometimes on the right notch

Doesn't matter. The fan should be off above 30. Shut off the switch if it's sustained 30mph

Way 1294 its alright. We really are an inclusive forum. He's just saying that it gets really confusing running 2 different Jeeps on the same thread> if you want help posting up to a new thread of your own just let us know. Serious, Welcome to the forum.

Every forum has its own etiquette. Some forums demand never making new threads. This one is friendlier. A new thread for every problem. It's faster and less confusing that way.

Okay quick update, drove to Dalls and it did it again, this time it didn't want to restart at all

What I did notice was that the engine wouldn't be starting at all and then I hear a light buzz from the fuel pump and then it starts, then dies

Which leaves me to believe it was the crank sensor all along

Should I replace the cam sensor while I'm at it?

The fuel pump should probe even if the sensor is bad. You need to look at the cluster and see if the check engine light is coming on immediately when you turn the key on or is it delayed until you hear the fuel pump. If it is delayed then you have an ecu on its way out. It's possible that you have 2 issues but the ecu is well documented. Post back if that's the case.

A battery reset will do the same thing and it will get worse quick. Replace it for sure.
