Does this plug looks bad?

I have 2005 Kia Sedona and this connects to the thing that another plug comes into it and it's neat radiator fan. The wire housing goes all the way and connects the pass headlight and other stuff. The issue with my car that after driving it and especially sitting at idle, the rpm goes up to 1500 and the car heats up to 3/4 the hi fan kicks on and. Cools it back down. Also the main issue is that when I go to start after I drive it it won't start. It is roll over or crank or what evee it's called. It doesn't sound like a deadness like only starter sound and it doesn't spit or sputter it backfire, just wont start up. I replaced the thermostat and the fuel pump. The mechanic said fuel temperature sensor, abnormal. Umm.. mainly i was wondering when passenger side kicks on. It doesn't kick on at normal operating temperature. Is it suppose to? I'm not entirely sure but it seems like when the driver side can kicks on, Its seems like all the air blowing comes from that side. Can't exactly tell if it's the air from that side but it seems like I'm feeling the air from the diver side coming over to passenger because I don't feel it centered on it. Also I ran alligator clips from battery to that fan and the fan ran.
